(x+2)(x-10)
so X=-2 , X=10

x^2 - 8x - 20 = 0
(x-10)(x+2) = 0
x-10 = 0: x = 10
x + 2 = 0: x = -2
Answer: x=10, x = -2

The answer is
x = -2 OR x = 10
Because X^2-8x-20 Factors, resulting in (X-10)(X+2), which are your two 'solutions' to the problem, simply reversing the sign to finalize them.

x^2-8x-20=0
(x-10)(x+2) = 0
x=10 and x = -2

x= -2 or x=10
Use the quadratic equation, and plug in values, or buy a TI-89.
