Find the possible value or values of r in the quadratic equation r2–7r–8=0. User: Find the possible value or values of z in the quadratic equation z2–4z+4=0.
Weegy: z^2 - 4z + 4 = 0 Factor to get: (z-2)(z-2) = 0 Since the product is zero, one of the factors must be zero: z-2 = 0 Therefore z = 2 Source: (More)

x^2 + 11x + 121 = x + 96;

x^2 + 11x - x + 121 - 96 = 0

x^2 + 10x + 25 = 0

Discriminant:
b^2 - 4ac
10^2 - 4(1)(25) = 100 - 100 = 0

–4j^2 + 3j – 28 = 0;
Discriminant:
b^2 - 4ac
3^2 - 4(-4)(-28) = 9 - 448 = -439

Number of solutions: No real solutions.
