(8y-3)(4y+1)=0

Solution for (8y-3)(4y+1)=0 equation:

Simplifying
(8y + -3)(4y + 1) = 0

Reorder the terms:
(-3 + 8y)(4y + 1) = 0

Reorder the terms:
(-3 + 8y)(1 + 4y) = 0

Multiply (-3 + 8y) * (1 + 4y)
(-3(1 + 4y) + 8y * (1 + 4y)) = 0
((1 * -3 + 4y * -3) + 8y * (1 + 4y)) = 0
((-3 + -12y) + 8y * (1 + 4y)) = 0
(-3 + -12y + (1 * 8y + 4y * 8y)) = 0
(-3 + -12y + (8y + 32y2)) = 0

Combine like terms: -12y + 8y = -4y
(-3 + -4y + 32y2) = 0

Solving
-3 + -4y + 32y2 = 0
