Simplifying
-5y(y + 6)(y + 2) = 0

Reorder the terms:
-5y(6 + y)(y + 2) = 0

Reorder the terms:
-5y(6 + y)(2 + y) = 0

Multiply (6 + y) * (2 + y)
-5y(6(2 + y) + y(2 + y)) = 0
-5y((2 * 6 + y * 6) + y(2 + y)) = 0
-5y((12 + 6y) + y(2 + y)) = 0
-5y(12 + 6y + (2 * y + y * y)) = 0
-5y(12 + 6y + (2y + y2)) = 0

Combine like terms: 6y + 2y = 8y
-5y(12 + 8y + y2) = 0
(12 * -5y + 8y * -5y + y2 * -5y) = 0
(-60y + -40y2 + -5y3) = 0
