(7x + 8)(7x - 9)
(4x - 3)(2x + 3)
(4x - 3)(2x + 3)
(3x + 1)(x - 4)
(5x+2) and (x-2)
(x + 9)(x -1)
(10x + 1)(x + 10)
9
If that's +32, the answer is (x - 4)(5x - 8)
If that's +72y, the answer is 2y(x - 9)(3x - 4)
The factors of 6x2+7x-5 are (3x+5) and (2x-1).
3x2-7x+4 = (3x-4)(x-1) when factored
x2 + 8x - 9 = (x + 9)(x - 1)
