If the question could more exactly be phrased as, "What is the value of x when 9x2 - 16 = 0", the answer is, x = 4 or -4. This answer can be found by factoring 9x2 - 16 into (3x + 4)(3x - 4) and setting each factor equal to zero.
Factor: 9x2 - 25.
If you mean: 9x2+3x-2 = (3x+2)(3x-1) when factored
9x2 + 9x - 10 =(3x - 2)(3x + 5)
9x2+2x-7 = (9x-7)(x+1) when factored
