Answer 1

None of the choices are correct.

Explanation:

`9x^3 + 9x^2 - 4x - 4 = 0`

The polynomial has 4 terms and no common factors. We can try factoring by grouping.

`9x^2(x + 1) - 4(x + 1) = 0`

`(x + 1)(9x^2 - 4) = 0`

Now we factor the difference of squares.

`(x + 1)(3x + 2)(3x - 2) = 0`

`x + 1 = 0~~or~~3x + 2 = 0~~or~~3x - 2 = 0`

`x = -1~~or~~x = -(2)/(3)~~or~~x = (2)/(3)`

None of the choices are correct.
