Answer:
x = 0 or -3/2
Step-by-step explanation:
(
2
x + 3
)
^2 − 6
x − 9 = 0 ---> distribute
4x^2 + 6x + 6x + 9 - 6x - 9 = 0 --> add the 9's together
4x^2 + 12x - 6x = 0 --> combine like terms
4x^2 + 6x = 0 --> common factor
2(2x^2 + 3x) = 0 --> divide by 2 on both sides
2x^2 + 3x = 0
then you should use the quadratic formula (can't add here or the explanation would take too long)
