Solution for y(2y-1)(y+4)= equation: 


Simplifying
y(2y + -1)(y + 4) = 0

Reorder the terms:
y(-1 + 2y)(y + 4) = 0

Reorder the terms:
y(-1 + 2y)(4 + y) = 0

Multiply (-1 + 2y) * (4 + y)
y(-1(4 + y) + 2y * (4 + y)) = 0
y((4 * -1 + y * -1) + 2y * (4 + y)) = 0
y((-4 + -1y) + 2y * (4 + y)) = 0
y(-4 + -1y + (4 * 2y + y * 2y)) = 0
y(-4 + -1y + (8y + 2y2)) = 0

Combine like terms: -1y + 8y = 7y
y(-4 + 7y + 2y2) = 0
(-4 * y + 7y * y + 2y2 * y) = 0
(-4y + 7y2 + 2y3) = 0

Solving
-4y + 7y2 + 2y3 = 0

Solving for variable 'y'.

Factor out the Greatest Common Factor (GCF), 'y'.
