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

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

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

Multiply (5 + y) * (6 + y)
-2y(5(6 + y) + y(6 + y)) = 0
-2y((6 * 5 + y * 5) + y(6 + y)) = 0
-2y((30 + 5y) + y(6 + y)) = 0
-2y(30 + 5y + (6 * y + y * y)) = 0
-2y(30 + 5y + (6y + y2)) = 0

Combine like terms: 5y + 6y = 11y
-2y(30 + 11y + y2) = 0
(30 * -2y + 11y * -2y + y2 * -2y) = 0
(-60y + -22y2 + -2y3) = 0

Solving
-60y + -22y2 + -2y3 = 0
