Lisa solves the equation below: x² + 4x - 12 = 2 (x - 2)(x + 6) = 2, by setting x -2 = 0 and x + 6 = 0. Her solutions are x = 2 and x = -6. Is Lisa correct? Why or why not?

• Yes, she factored correctly.

• Yes, she factored correctly and then square rooted.

• No, she did factor correctly, but solved it wrong. It should be equal to 2

• No, she didn't set the equation to zero.
