How Quadratic Roots Work

Quadratic equations are solved using the quadratic formula:

$x = \frac{-b \pm \sqrt{b^2 – 4ac}}{2a}$x=2a−b±b2−4ac​​

$a$a

$b$b

$c$c-10-8-6-4-2246810-10102030-2.002.00

The discriminant determines the type of roots.

If the Discriminant Is Positive

The equation has two real roots.

If the Discriminant Is Zero

The equation has one repeated real root.

If the Discriminant Is Negative

The equation has imaginary or complex roots.

Example:

$x^2 + 2x + 5 = 0$x2+2x+5=0

This equation produces complex roots because the discriminant is negative.
