3x squared - (3x) squared = 0
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
Subtract 5 from each side: 16 = 5x + 3x ie 16 = 8xDivide each side by 8: 2 = x21 = 5x + 3x + 521 - 5 = 8x16 = 8x16/2 = x2 = xx = 2Check:21 = 5(2) + 3(2) + 521 = 10 + 6 + 521 = 21
The given expression can be simplified to: 3X squared +27
3x(6x - 1)
3x squared - (3x) squared = 0
3x squared - x squared = 2x squared
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
That factors to 3x(3x - 1)
Subtract 5 from each side: 16 = 5x + 3x ie 16 = 8xDivide each side by 8: 2 = x21 = 5x + 3x + 521 - 5 = 8x16 = 8x16/2 = x2 = xx = 2Check:21 = 5(2) + 3(2) + 521 = 10 + 6 + 521 = 21
(3x-2y)2=
The given expression can be simplified to: 3X squared +27
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)
If that's -18y2, the answer is (3x - 2y)(x + 9y)
3x squared minus 25x minus 28
2 squared X 3 squared = 5 squared
