(2y-1)(2y+3)=

Solution for (2y-1)(2y+3)= equation:

Simplifying
(2y + -1)(2y + 3) = 0

Reorder the terms:
(-1 + 2y)(2y + 3) = 0

Reorder the terms:
(-1 + 2y)(3 + 2y) = 0

Multiply (-1 + 2y) * (3 + 2y)
(-1(3 + 2y) + 2y * (3 + 2y)) = 0
((3 * -1 + 2y * -1) + 2y * (3 + 2y)) = 0
((-3 + -2y) + 2y * (3 + 2y)) = 0
(-3 + -2y + (3 * 2y + 2y * 2y)) = 0
(-3 + -2y + (6y + 4y2)) = 0

Combine like terms: -2y + 6y = 4y
(-3 + 4y + 4y2) = 0

Solving
-3 + 4y + 4y2 = 0
