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

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

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

x^2 + 10x + 25 = 0

Discriminant:

b^2 - 4ac

10^2 - 4(1)(25) = 100 - 100 = 0
