Solve.
9x^2 + 12x = 32
x2 + (4/3)x - (32/9) = 0
has two solutions:
x = -2/3 + √ 4
or
x = -2/3 - √ 4
This is the solution I came up with. Is this right?? Please and Thank you.

9x^2 +12x -32 0
(3x + 8) (3x -4) =0
3x + 8 = 0
3x - 4 = 0
x = -8/3
x = 4/3
(3x + 8) (3x -4) =0
3x + 8 = 0
3x - 4 = 0
x = -8/3
x = 4/3
