Question

Understand and represent real life situation involving quadratic equation ​

Answer 1

Given :- When are the roots of a quadratic equation real and equal.

To Find :- When roots of a quadratic equation real and equal.

Solution :-

When a, b, and c are real numbers, a ≠ 0 and the discriminant is zero, then the roots α and β of the quadratic equation $ax {}^{2} + bx + c = 0$are real and equal.

Hence, the final answer is

When a, b, and c are real numbers, a ≠ 0 and the discriminant is zero, then the roots α and β of the quadratic equation $ax {}^{2} + bx + c = 0$are real and equal.
