(2x + 1)(2x - 1)
4(x - 1)(x + 1)
4(x + 1)(x - 1)
(2x - 1)(4x2 + 2x + 1)
(2x2 - 1)(2x2 - 1) or (2x2 - 1)2
(4x + 3)(x - 1)
The quadratic 4x2+24x+11 = (2x+1)(2x+11)
4x2 - 9y Not factorable from what I see.
The GCF is 4x2.
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) (4x + 2y)(x - 1).
(2x + 3)(2x - 1)
(2x - 1)(2x + 5)
