-3x(2x - 1)(2x + 1)
(2x + 3y)(2x + 5y)
It can be. x^2 + x + 1 is a factor of 2x^2 + 2x + 2
(2x+3)(2x+4)
(x + 1)(2x + 5)
(2x+1)(2x+3) when factored
4(2x + 3y)(2x + 3y)
(2x + 1)(x + 2)
(2x + 1)(2x + 1) or (2x + 1)2
If that was 2x^2 + 5x + 2, it would factor to (2x + 1)(x + 2)
(2x + 3)(2x + 3)
(2x + 3)(x + 1)
