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

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

Multiply (2 + y) * (-6 + 5y)
(2(-6 + 5y) + y(-6 + 5y)) = 0
((-6 * 2 + 5y * 2) + y(-6 + 5y)) = 0
((-12 + 10y) + y(-6 + 5y)) = 0
(-12 + 10y + (-6 * y + 5y * y)) = 0
(-12 + 10y + (-6y + 5y2)) = 0

Combine like terms: 10y + -6y = 4y
(-12 + 4y + 5y2) = 0
