4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
If that's + 80, the answer is -4(x + 5)(x - 4)
Take out the common factor, 3: 3x + 6 = 3(x + 2).
(x + 3)(4x + 5)
(x - 5)(x - 3)
(2x - 1)(2x + 5)
4x2-8x-5 (2x+1)(2x-5)
(2x + 5)(4x2 - 10x + 25)
4(x^2 + 2x - 5)
If that's + 4x2, the answer is 2x(x2 + 2x - 4)
x(7x ^2 - 4x + 8)
4(x^2 + 8x + 160)
(2x - y2)(4x2 + 2xy2 + y4)
(2x - 1)(4x2 + 2x + 1)
4(x + 1)(x + 1)
4(x^2 + 2x + 8)
(2x - 1)(2x + 5)
