Step-by-step explanation:

If a quadratic equation ax Square + bx + c = 0, where a, b, c are real numbers and a is not equal to zero, has real and equal roots then

{b}^{2} - 4ac = 0

If a quadratic equation ax Square + bx + c = 0, where a, b, c are real numbers and a is not equal to zero, has real and unequal roots then

{b}^{2} -4ac \geq 0

If a quadratic equation ax Square + bx + c = 0, where a, b, c are real numbers and a is not equal to zero, has non-real roots then

{b}^{2} - 4ac \leq 0
