3x2-2x-8 = (3x+4)(x-2) when factored
3x squared - (3x) squared = 0
3
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
The given expression can be simplified to: 3X squared +27
3x(6x - 1)
3x squared - (3x) squared = 0
x=4 or x=-4
3
That factors to 3x(3x - 1)
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
(3x-2y)2=
The given expression can be simplified to: 3X squared +27

3X2 - 3X 3X(X - 1) -----------------------factored, so 3X is gfc
If that's -18y2, the answer is (3x - 2y)(x + 9y)
3x squared minus 25x minus 28
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
