Without an equality sign the given terms of an expression can't be classed as an equation and so therefore an answer is not possible.
If: 3x-3 = 7x+21 Then: x = -6
x2 + 7x + 6 = (x + 6) (x + 1)
It is: 12x2-7x-12 equals (4x+3)(3x-4) when factored
If you mean: x squared -7x +12 then it is (x-3)(x-4) when factored
7(x - 2y)
It is: 7(x+2y)
The GCF is 7.
set it up as x+5y=10 and 7x-14y=49 on top of each other and then multiply x+5y=10 by -7. That gives you -7x-35y=-70. cross out the X's and add the Y's. -21y=21 divide and get -1=y then sub. for x and solve. X=15 and X=5

Since 7x is a factor of 14xy, it is automatically the GCF.
(y-12)(y-2)
(3y - 2)(y - 4)
(7x + 8)(7x - 8)
12x - 4 = 7x - 21 12x -7x = -21 + 4 5x = -17 x = -3.4
(7x + 8)(7x - 9)
If: 3x-3 = 7x+21 Then: x = -6
