# NCERT Solutions Class 10 Maths Chapter 4 Quadratic Equations

NCERT solutions for class 10 maths chapter 4 Quadratic Equations deal with the concept of quadratic equations and the different ways of finding their roots. A quadratic equation is represented as ax^{2} + bx + c = 0 , where a, b, c are the values of real numbers, and the value of ‘a’ is not equal to zero. This is also known as the standard form of the quadratic equation. An interesting fact to note is that many people believe that Babylonians were the first to solve quadratic equations. For instance, they knew how to find two positive numbers with a given positive sum and a given positive product, and this problem is equivalent to solving a quadratic equation. Moreover, the Greek mathematician Euclid developed a geometrical approach for finding out lengths which, in our present-day terminology, are solutions of quadratic equations The NCERT solutions class 10 maths chapter 4 Quadratic Equations teaches kids how to solve these equations by the factorization method and completing the square method. Students will come across important formulas like the quadratic formula for finding the roots of the equation.

The major takeaways from this chapter would be that for a quadratic equation two real roots will be distinct, if b^{2} – 4ac > 0 ; two coincident roots will be obtained, if b^{2} – 4ac = 0 ; and no roots will be there, if b^{2} – 4ac < 0. The students will also explore how quadratic equations can be applied to real-life situations.
