## Important Formulas| RD Sharma Class 10 Chapter-8

1. Quadratic Formula: For a given quadratic equation ax2 + bx + c = 0, you can find its roots using the formula given below.

x = (-b ± √b2 - 4ac)/ 2a, given that b2 - 4ac ≥ 0

2. When you solve a quadratic equation ax2 + bx + c = 0, you may obtain one of the three results mentioned below.

(a). Two different real roots, if b2 - 4ac > 0

(b). Two roots having same values, if b2 - 4ac = 0

(c). No real roots, in case you obtain b2 - 4ac < 0

## Concepts in RD Sharma Class 10 Chapter-8

In the beginning of Chapter-8, you have learnt to represent the quadratic equation in standard form. Next, you also got familiar with finding the roots of the equation by factorization using middle-term splitting. Alternate method of solving a quadratic equation is to complete the square.
