## How Polynomial Equation Solver Calculator Works?

A **polynomial** is defined as a type of expression in which the exponents of the variable should be a whole number.

A polynomial with a degree of 1 is known as a linear polynomial.

A polynomial with a degree of 2 is known as a quadratic polynomial.

A polynomial with a degree of 3 is known as a cubic polynomial.

A polynomial with a degree of 4 is known as a quartic polynomial.

A polynomial with a degree of 5 is known as a quintic polynomial.

A polynomial with a degree(n) greater than 5 is known as an nth degree polynomial.

A polynomial with any degree equates it to zero and finds the value of x for a given polynomial.

Let us understand this with the help of the following example.

**Solved Examples on Polynomial Equation Solver Calculator**

**Example 1:**

Solve the value of x for given x^{2} - 25 = 0 and verify it using the polynomial equation solver calculator?

**Solution**:

x^{2} - 25 = 0

x^{2} = 25

x = +5, -5

Therefore, the value of x is -5 and 5

**Example 2:**

Solve the value of x for given x^{3} + 64 = 0 and verify it using the polynomial equation solver calculator?

**Solution**:

x^{3} + 64 = 0

x^{3} = -64

x^{3} = (-4)^{3}

x = -4

Therefore, the value of x is -4

Now, try the polynomial equation solver calculator and find the value of x for:

- 5x
^{4}- 4x + 9 = 0 - 9x
^{2}+ 4 = 0
