# NCERT Solutions Class 10 Maths Chapter 4 Exercise 4.3 Quadratic Equations

NCERT solutions for class 10 maths chapter 4 exercise 4.3 Quadratic Equations will help the students master the concepts of solving a quadratic equation by completing a square and applying the quadratic formula to derive the roots of a quadratic equation. If any quadratic equation can be converted to the form of (x + a)^{2} – b^{2} = 0, then it becomes easy to find its roots. This is known as the method of completing the square.

The students must also practice learning the formula to find the roots of the equation ax^{2} + bx + c = 0 which is :

x = [-b ± √(b^{2} - 4ac)] / 2a

With the help of this NCERT solutions class 10 maths chapter 4 exercise 4.3, kids will get to learn the application of the quadratic formula and how it can be analyzed further to draw logical conclusions. Apart from this, they also learn how to convert a mathematical equation in the form of a square and identify the nature of the roots. This exercise has 11 questions based on these concepts.

## NCERT Solutions Class 10 Maths Chapter 4 Exercise 4.3 Tips

NCERT solutions class 10 maths chapter 4 exercise 4.3 Quadratic Equations enables the students to draw a comparison between two methods to find the roots of a quadratic equation. The first being completing the squares and the second is applying the quadratic formula. The students are advised to be thorough with the concept and calculations involving square roots to progress through the exercise questions smoothly.

NCERT solutions for class 10 maths chapter 4 exercise 4.3 Quadratic Equations outlines certain important conditions for taking out the roots apart from remembering the quadratic formula; like if the value of b^{2} – 4ac ≥ 0, in that case, the roots of the quadratic equation: ax^{2} + bx + c = 0 are given by [-b ± √(b^{2} - 4ac)] / 2a

Using the quadratic formula is one of the fastest methods to calculate the roots of a quadratic equation. Referring to the examples can be pretty helpful in understanding this method. Additionally, if not specified in the questions kids should aim at using this technique to solve the problem.
