(2) Real and equal (i. e., repeated roots), if D = 0.

Step-by-step explanation:

. In a quadratic equation ax2 + bx + c = 0, if discriminant is D = b2 - 4ac, then roots of the quadratic equation are

Real and equal (i. e., repeated roots), if D = 0.

If the D > b² - 4ac then it's real and distinct.
