The given expression can be simplified to: 3X squared +27
3x squared - (3x) squared = 0
(12x2 + 18) / (3x2 + 6) = (4x2 + 6) / (x2 + 2)
That factors to (x - 3)(x + 6)
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
The given expression can be simplified to: 3X squared +27
If that's -18y2, the answer is (3x - 2y)(x + 9y)
3x squared - (3x) squared = 0
3x squared - x squared = 2x squared
(12x2 + 18) / (3x2 + 6) = (4x2 + 6) / (x2 + 2)
That factors to (x - 3)(x + 6)
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
That factors to 3x(3x - 1)
(3x-2y)2=
I got 441. -9 x 2 = -18. -18 - 3 = 21 21 x 21 = 441
3X2 - 3X 3X(X - 1) -----------------------factored, so 3X is gfc
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
