Simplifying
(3 + y)(5y + -7) = 0

Reorder the terms:
(3 + y)(-7 + 5y) = 0

Multiply (3 + y) * (-7 + 5y)
(3(-7 + 5y) + y(-7 + 5y)) = 0
((-7 * 3 + 5y * 3) + y(-7 + 5y)) = 0
((-21 + 15y) + y(-7 + 5y)) = 0
(-21 + 15y + (-7 * y + 5y * y)) = 0
(-21 + 15y + (-7y + 5y2)) = 0

Combine like terms: 15y + -7y = 8y
(-21 + 8y + 5y2) = 0
