Solve Now   ## Discriminants and determining the number of real roots of a

So when the discriminant of a quadratic equation is less than 0, it has two roots which are distinct and complex numbers (non-real). If Discriminant is Equal to Zero If D = 0, the quadratic equation has two equal real roots. In other words

The discriminant for this equation is: Discriminant = b 2 − 4 a c Discriminant = 2 2 − 4 ⋅ 1 ⋅ ⋅ 1 Discriminant = 4 − 4 Discriminant = 0 Since the discriminant is zero, there should be 1 real solution to this equation. Below is a picture representing

A quadratic equation can be defined as a polynomial equation that has a degree of 2. ax 2 + bx + c = 0 where a and b are the coefficients, x is the unknown variable and c is the constant, and a ≠ 0. Discriminant Formula for Solving a Quadratic Equation Since a quadratic equation has a degree of 2, therefore it will have two solutions.
