## How do you find all roots of a quadratic equation?

**For a quadratic equation ax**

^{2}+ bx + c = 0,- The roots are calculated using the formula, x = (-b ± √ (b² – 4ac) )/2a.
- Discriminant is, D = b
^{2}– 4ac. If D > 0, then the equation has two real and distinct roots. If D < 0, the equation has two complex roots. … - Sum of the roots = -b/a.
- Product of the roots = c/a.
