WebNov 15, 2024 · So there must be 2 non-real roots. If 1 root is real, then the discriminant is either + or 0. What does it mean if the discriminant has equal roots? If the discriminant is equal to zero, this means that the quadratic equation has two real, identical roots. Therefore, there are two real, identical roots to the quadratic equation x2 + 2x + 1. WebCase 2 – D = 0 If D is equal to 0, then the roots are equal and real. Case 3 – D > 0 If D is greater than 0, then both the roots are real and distinct. To find both the roots, we use the formula given below – Root1 = ( -B + square_root(D) ) / 2A Root2 = ( -B – square_root(D) ) / 2A. Program to find roots of a quadratic equation in C++
