The GCF is 15x.

2(5x - 1)(3x - 2)

The GCF of 30 x^2 and 45x is 15x. The GCF of 30 and 45 is 15, and the GCF of x squared and x is x.

The GCF is 15x^3.

The GCF is 15x^2y^2

5x(6x + 7y + 8)

5(7x^2y + 6x^2 + 8)

If x>1 then the gcf is 15x. If x<1 then the gcf is 15.

Two possibilities here. 9x - 30x +25 = -21x + 25 and done, but I don't think you mean that. 9x² - 30x + 25 is more likely. This is easier than normal, since this follows the square pattern. (ax-b)² = a²x²-2ab+b² a² = 9 so a=3 b² = 25 so b=5 3*5*2 = 30, so it checks. (3x-5)(3x-5) = 9x² -15x - 15x + 25 = 9x² -30x + 25 ■

The GCF of 24x and 30x is 6x.

2x2 - 30x - 152 = 0 simplify x2 - 15x - 76 = 0 since -76 = -19 x 4 and -19 + 4 = -15, we have (x + 4)(x - 19) = 0 x + 4 = 0 or x - 19 = 0 x = -4 or x = 19
