solvingEquations

Solving a given quadratic equation. The nature of the roots are given as, If discriminant>1 then the roots are real and different If discriminant=0 then the roots are real and equal If discriminant<1 then the roots are complex and different For the quadratic equation ax² + bx + c = 0, if we denote the discriminant as d, then their roots

If d>1 then the roots are real and different root1 = (-b + √d)/2a root2 = (-b – √d)/2a If d=0 then both roots are -b/2a

If d<1 then roots are complex and different root1 = -b/2a + i (√d/2a) root2 = -b/2a – i (√d/2a)
