What is Algebra 1?
Algebra 1 consists of the general/basic concepts of algebra. It introduces evaluating equations and inequalities, real numbers, and their properties, which include additive and multiplicative identities, inverse operations, and the distributive and commutative properties. In algebra 1, we will also be introduced to the concept of polynomials, and will also incorporate a bit of geometry to calculate the area, volume, and perimeters of shapes using algebraic expressions instead of numbers.
Algebra 1 or elementary algebra deals with solving the algebraic expressions for a viable answer. In algebra 1, simple variables like x, y, are represented in the form of an equation. Based on the degree of the variable the equations can be categorized into different types, namely linear equations, quadratic equations, cubic equations, and so on. Linear equations are of the forms of ax + b = c, ax + by + c = 0, ax + by + cz + d = 0. Elementary algebra based on the degree of the variables, branches out into quadratic equations and polynomials. A general form of representation of a quadratic equation is ax^{2} + bx + c = 0, and for a polynomial equation, it is ax^{n }+ bx^{n1}+ cx^{n2}+ .....k = 0.
The rules for different properties under algebra 1 can be understood better as shown below,

Laws of Algebra 1
The basic laws of algebra are the associative, commutative, and distributive laws that are presented in the table below:
Property Name  Definition  Example 

Commutative Law For Addition 
(a + b) = (b + a). According to the commutative property, swapping the positions of operands in an operation does not affect the result. 
If (4x + 3x) = 7x, then (3x + 4x) = 7x 
Commutative Law For Multiplication 
(a × b) = (b × a). According to the commutative property, swapping the positions of operands in an operation does not affect the result. 
If (2x × 4) = 8x, then (4 × 2x) = 8x 
Associative Law For Addition 
a + (b + c) = (a + b) + c. This grouping of addends does not affect the sum. 
If 3y + (4y + 5y) = (3y + 9y) = 12y, then (3y + 4y) + 5y = 7y + 5y = 12y 
Associative Law For Multiplication 
a × (b × c) = b × (a × c). This grouping of factors does not affect the product. 
If 3a × (2b × 5c) = 3a × (10bc) = 30abc, then, (3a × 2b) × 5c = 6ab × 5ac = 30abc 
Distributive Law For Addition 
a × (b + c) = (a × b) + (a × c). Adding two numbers and then multiplying them with a third gives the same result as multiplying the two numbers individually to the third and thereafter adding the obtained result. 
If 4x × (3y + 2y) = (4x × 5y) = 20xy, then (4x × 3y) + (4x × 2y) = 12xy + 8xy = 20xy 
a × (b  c) = (a × b)  (a × c). Subtracting two numbers and then multiplying them with a third gives the same result as multiplying the two numbers individually to the third and thereafter subtracting the obtained result.  If 4x × (3y  2y) = (4x × y) = 4xy, then (4x × 3y)  (4x × 2y) = 12xy  8xy = 4xy 
Algebra 1 Formulas
Here are the list of formulas that are very useful in solving Algebra 1 problems.
 Algebraic identities:
(a + b)^{2} = a^{2} + 2ab + b^{2}
(a  b)^{2} = a^{2}  2ab + b^{2}
(a + b)(a  b) = a^{2}  b^{2}
(x + a)(x + b) = x^{2} + x(a + b) + ab
(a + b)^{3} = a^{3} + 3a^{2}b + 3ab^{2} + b^{3}
(a  b)^{3} = a^{3}  3a^{2}b + 3ab^{2}  b^{3}
a^{3} + b^{3} = (a + b)(a^{2}  ab + b^{2})
a^{3}  b^{3} = (a  b)(a^{2} + ab + b^{2})
(a + b + c)^{2} = a^{2} + b^{2} + c^{2} + 2ab + 2bc + 2ca  Properties of Exponents:
a^{m}. a^{n} = a^{m + n}
a^{m}/a^{n} = a^{m  n}
(a^{m})^{n} = an
(ab)^{m} = a^{m}. b^{m}
a^{0} = 1
a^{m} = 1/a^{m}  Linear Equations Formulas:
General form: ax + by = c
Slope Intercept Form: y = mx + b
TwoPoint Form: y−y_{1}=m(x−x_{1})
Intercept Form: x/a + y/b = 1
Vertical Line through (p, q): x = p
Horizontal Line through (p, q): y = q  Quadratic Equations Formulas:
The standard form of quadratic equation is ax^{2} + bx + c = 0
Vertex form of quadratic equation is a (x  h)^{2} + k = 0
Quadratic Formula: The roots of a quadratic equation ax^{2} + bx + c = 0 are given by x = [b ± √(b²  4ac)]/2a.  Arithmetic Sequence Formulas:
n^{th} term, a_{n}=a_{1}+(n−1)d
Sum = n/2 [2a + (n  1) d] (OR) n/2 [a_{1} + a_{n}]  Geometric Sequence Formulas:
The n^{th} term of the geometric sequence is, a_{n} = a · r^{n  1}.
Sum of n terms, S_{n} = a (r^{n}  1) / (r  1)
Sum of infinite terms, S = a / (1  r)  Average rate of change formula: [f(b)  f(a)] / (b  a)
 Compound Interest Formula: A = P (1 + r / n)^{n t}
 Statistics Formulas:
Mean = (Sum of Observations) ÷ (Total Numbers of Observations)
Mean of Grouped Data = Σf_{i}/N
Median when 'n' is odd: [(n + 1)/2]^{th} term; Median when 'n' is even: [(n/2)^{th} term + ((n/2) + 1)^{th} term]/2
Range = Maximum  Minimum
Interquartile Range = Upper quartile  Lower quartile
Difference Between Algebra 1 and Algebra 2
Algebra 1 and Algebra 2 can be distinguished based on the complexity and use of algebraic expressions. The following table explains the important differences between algebra 1 and algebra 2.
Algebra 1  Algebra 2 

Algebra 1 introduces you to the general concepts of algebra. You learn about variables, functions, and the most important concept in all of algebra.  Algebra 2 is much more advanced. It's also much more miscellaneous: you learn about everything from logarithms and complex numbers to implicit functions and conics to the fundamental theorem of algebra. 
Algebra 1 helps students to have the basic command in algebra topics.  Algebra 2 increases complexity and understanding of the topics learned in algebra 1. 
In this, students learn how to manipulate exponents or polynomials and write them in simpler forms, etc.  In this, students learn to apply the skills thus obtained in algebra 1 and also learn more difficult techniques. 
Algebra 1 is concentrated on solving equations and inequalities  Algebra 2 concentrates on additional types of equations, such as exponential and logarithmic equations. 
Algebra 1 is essential to understand algebra 2.  Algebra 2 is essential for understanding concepts coming on calculus. 
Tips and Tricks on Algebra 1
 To understand Algebra 1, we need to be familiar with the prealgebra topics like integers, onestep equations, multistep equations, inequalities and equations, graphs and functions, percent, probabilities, an introduction to geometry, and, right triangles. Once we go through a refresher, then we can proceed to algebra 1.
 When multiplying two rational expressions in algebra, there is always a risk of getting false solutions or extraneous solutions so be careful with your calculations part.
 We can add polynomials by just adding the like terms to combine the two polynomials into one.
Important Notes on Algebra 1:
 The addition property of inequality: Adding the same number to each side of the inequality produces an equivalent inequality.
 Negative exponents: The reciprocals of the positive exponents in exponential functions.
 The quotient of powers property: It tells us that when we divide the powers with the same base we just have to subtract the exponents.
 The constants have a monomial degree of 0.
