(3x + 8)(3x - 8)
It is a difference of squares. 9x^2-49=(3x+7)(3x-7)
This is a difference of two squares, which factorises to: (3x - 4y)(3x + 4y)
3x squared minus 25x minus 28
(3x-4)(3x+4)
9x2-9x-10 = (3x+2)(3x-5) when factored
(3x + 8)(3x - 8)
It is a difference of squares. 9x^2-49=(3x+7)(3x-7)
(x + 3)(3x - 2)
This is a difference of two squares, which factorises to: (3x - 4y)(3x + 4y)
(x + 2)(3x - 1)(3x + 1)
9x2 - 6xy + y2 - 81 = (3x - y)2 - 92 = (3x - y - 9)(3x - y + 9)
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)

3x squared minus 25x minus 28
(3x-4)(3x+4)
x2-9x can be factored by taking x out of each term x(x-9)
