Question

In the equation ax² + bx + c = 0, it is given that D = (b² – 4ac) > 0. Then, the roots of the equation are ______.

Options

• real and equal

• real and unequal

• imaginary

• none of these

Answer 1

In the equation ax² + bx + c = 0, it is given that D = (b² – 4ac) > 0. Then, the roots of the equation are real and unequal.

Explanation:

We know that when discriminant, D > 0, the roots of the given quadratic equation are real and unequal.
