Simplifying
(y + -12)(2y + 14) = 0

Reorder the terms:
(-12 + y)(2y + 14) = 0

Reorder the terms:
(-12 + y)(14 + 2y) = 0

Multiply (-12 + y) * (14 + 2y)
(-12(14 + 2y) + y(14 + 2y)) = 0
((14 * -12 + 2y * -12) + y(14 + 2y)) = 0
((-168 + -24y) + y(14 + 2y)) = 0
(-168 + -24y + (14 * y + 2y * y)) = 0
(-168 + -24y + (14y + 2y2)) = 0

Combine like terms: -24y + 14y = -10y
(-168 + -10y + 2y2) = 0
