Question

What is the formula to find the discriminant in a quadratic equation?

Answer 1

The discriminant of a quadratic equation can be found using the formula:
`discriminant = b² - 4ac`. It helps determine the nature of the roots.

Step-by-step explanation:

The discriminant of a quadratic equation
`ax² + bx + c = 0` can be found using the formula:
`discriminant = b² - 4ac`.

The discriminant is a useful quantity in determining the nature of the roots of a quadratic equation. If the discriminant is greater than 0 the equation has two distinct real roots. If the discriminant is equal to 0, the equation has a repeated real root. If the discriminant is less than 0 the equation has two complex conjugate roots.
