16x² - 24x + 9 factors to (4x - 3)(4x - 3) or (4x - 3)2

Would have helped to have signs, but here's are two possible solutions:
(4x + 3)(4x + 3) or (4x - 3)(4x - 3) depending on whether 24x is positive or negative.
(4x + 3)(4x + 3) (4x + 3)2
(x - 3)(x - 9)
(x - 9)(x - 4)
I also need to know the answer to this problem. Can anyone answer it?
(x^2) + 24x + 144 = -9 x = -12
