The GCF is 9.
The GCF is 3.
The GCF is 3.
it is a combination of perfect squares the square of 9x is squared is +/- 3x, and the square of 4 is +/- 2 so the answer is (3x+2)(3x-2) which is 9xsquared-6x+6x-4 =9xsquared-4

3x. 15x - 9x = 6x 9x - 6x = 3x 6x - 3x = 3x 3x - 3x = 0

9x-11 = 6x+1 9x-6x = 1+11 3x = 12 x = 4
6x + 47 = 9x + 11 6x + 36 = 9x 36 = 3x 12 = x
it is a combination of perfect squares the square of 9x is squared is +/- 3x, and the square of 4 is +/- 2 so the answer is (3x+2)(3x-2) which is 9xsquared-6x+6x-4 =9xsquared-4
