Those 2 roots are given by the equation x = -b ± √(b2 -4ac) / 2a

**Further, the questions in SSC wont ask you directly to find the roots. Instead he may ask:**

a) Sum of Roots of a quadratic equation = -b/a

b) Product of the roots of a quadratic equation= c/a

**Important Concept about the roots:**

While finding roots if following conditions are satisfied, then the nature of the roots is as follows:

- When b2 -4ac <0, the roots are complex and unreal

- When b2 -4ac = 0, the roots are equal and real

- When b2 -4ac > 0, the roots are real and unequal

**Maximum and Minimum values of a quadratic Equation:**-Quadratic equation will have minimum value whenever a>0

-Quadratic equation will have maximum value whenever a<0
