Question

Stuck on a timed test!!! I cant figure this one out!!
Use the zero product property to find the solutions to the equation x2 – 15x – 100 = 0.
x = –20 or x = 5
x = –20 or x = –5
x = –5 or x = 20
x = 5 or x = 20

Answer 1

You have to factor the equations first.

Answer 2

\(\large\color{black}{ \displaystyle x^2 - 15x - 100 = 0 }\)
\(\large\color{black}{ \displaystyle x^2 - 5x-20x - 100 = 0 }\)
\(\large\color{black}{ \displaystyle x(x - 5)-20(x + 5) = 0 }\)

Answer 3

then complete the factoring (I got it half way through for you)
