That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: Zero plus or minus -0.5 times the square root of 2
x = -0.7071067811865476
x = 0.7071067811865476
2x(2x - 1)
(2x - 1)(2x + 1)
9(2x - 1)(2x + 1)
(2x - 1)(4x + 1)
2x squared - 5x - 3 = (2x +1)(x -3)
(x + 1)(2x - 5)
x(x + 2)
(x - 1)(2x - 9)
(x + 1)(2x + 5)
(2x-3)(x-1)
(2x + 1)(x + 2)
