4x2-4x-120 = (2x+10)(2x-12) when factored
It can be. 2x is a factor of 4x.
2x(2x - 1)
5-4x=12-2x isolate your x's on one side 5=12-2x+4x 5-12=-2x+4x simplify -7=2x divide by 2 x=-7/2, or x=-3.5
-2x=-4x*24 x=12
4x2-4x-120 = (2x+10)(2x-12) when factored
4x2-4x-120 = (2x+10)(2x-12) when factored
It can be. 2x is a factor of 4x.
(2x - 4)(2x + 3) The key is to look for all the factor pairs of 12.
(2x+3)(2x+4)
If that's - 4x, the answer is (2x + 3)(2x - 5) If that's + 4x, the answer is (2x - 3)(2x + 5)
(2x-1)(2x-1) = 4x^2 -4x + 1
2x(2x - 1)
5-4x=12-2x isolate your x's on one side 5=12-2x+4x 5-12=-2x+4x simplify -7=2x divide by 2 x=-7/2, or x=-3.5
-2x=-4x*24 x=12
2x-3=4x+9 -2x-12=0 2x=-12 x=-6
(2x + 3)(2x - 5)
