Answer 2

Answer:

None of the choices are correct.

Step-by-step 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.

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

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

$x = -1~~or~~x = -\dfrac{2}{3}~~or~~x = \dfrac{2}{3}$

None of the choices are correct.
