4
4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
Take out the common factor, 3: 3x + 6 = 3(x + 2).
No 9xx-18x+36 9(xx-2x+4) xx-2x+4 (doesn't factor evenly)
The GCF of 2x and 12 is 2.
(2x+3)(2x+4)
4(2x + 3y)(2x + 3y)
(2x + 1)(x + 4)
(2x+4)(x+1)
(2x - 1)(x + 4)
2(x+4)
(2x-4)(x-1) = 0
4
Factor it out: (x+2) squared
It is: 2(x+4) when factored
2x2 + 11x + 12 = 2x2 + 3x + 8x + 12 = x*(2x + 3) + 4*(2x + 3) = (2x + 3)*(x + 4)
(3x + 4)(2x - 1)
