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

Ox=-9

Ox = - 3

Ox = 0

Ox = 6

x = 0 or x = - 6

Step-by-step explanation:

Solve for x:

(x - 3) (x + 9) = - 27

Expand out terms of the left hand side:

x^2 + 6 x - 27 = - 27

Add 27 to both sides:

x^2 + 6 x = 0

Factor x from the left hand side:

x (x + 6) = 0

Split into two equations:

x = 0 or x + 6 = 0

Subtract 6 from both sides:

Answer: x = 0 or x = - 6
