Which is a solution to (x – 3)(x + 9) = –27?

x = –9
x = –3
x = 0
x = 6

If you would like to solve (x – 3)(x + 9) = –27, you can do this using the following steps:

(x – 3)(x + 9) = –27
x^2 + 9x - 3x - 27 = -27
x^2 + 6x - 27 + 27 = 0
x^2 + 6x = 0
x * (x + 6) = 0
1. x = 0
2. x = -6

The correct result would be x = 0.
