4x2-4x+1 = (2x-1)(2x-1)
(4x2 - 13x - 12)/(4x+ 3) = (4x + 3)(x - 4)/(4x + 3) = (4x + 3)(x - 4)/(4x + 3) = x - 4 :)
(4x-3)(x+2)
4x - 10 = -4x + 22 +4x+10=+4x +10 8x = 32 x = 4
6x + 10 + 4x = 5010x + 10 = 5010x = 40x = 4
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) (4x + 2y)(x - 1).
4x2-4x-120 = (2x+10)(2x-12) when factored
4x2-4x-120 = (2x+10)(2x-12) when factored
4x2 - 23xy + 15y2 = (4x - 3y)(x - 5y)
(2x + 3)(2x - 1)
-((4x + 1)(x - 1))
4x2+49x+90 = (4x+9)(x+10) when factored
4x2+2x-20 2x2+x-10 2x2+5x-4x-10 x(2x+5)-2(2x+5) (x-2)(2x+5)
4x2-4x+1 = (2x-1)(2x-1)
(2x + 1)(2x + 1) or (2x + 1)2
ANSWER: -4X2 -8X-4x (x+2)= (-4x * x) + (-4x*2)= -4X2 -8X
If you can't factor it easily, use the quadratic formula.
