((1 + -2y) + 2y * (-1 + 2y))(-1 + 2y) = 8
(1 + -2y + (-1 * 2y + 2y * 2y))(-1 + 2y) = 8
(1 + -2y + (-2y + 4y2))(-1 + 2y) = 8

Combine like terms: -2y + -2y = -4y
(1 + -4y + 4y2)(-1 + 2y) = 8

Multiply (1 + -4y + 4y2) * (-1 + 2y)
(1(-1 + 2y) + -4y * (-1 + 2y) + 4y2 * (-1 + 2y)) = 8
((-1 * 1 + 2y * 1) + -4y * (-1 + 2y) + 4y2 * (-1 + 2y)) = 8
((-1 + 2y) + -4y * (-1 + 2y) + 4y2 * (-1 + 2y)) = 8
(-1 + 2y + (-1 * -4y + 2y * -4y) + 4y2 * (-1 + 2y)) = 8
(-1 + 2y + (4y + -8y2) + 4y2 * (-1 + 2y)) = 8
(-1 + 2y + 4y + -8y2 + (-1 * 4y2 + 2y * 4y2)) = 8
(-1 + 2y + 4y + -8y2 + (-4y2 + 8y3)) = 8
