3(28 + -39y + 5y2)(9 + y) = 0

Multiply (28 + -39y + 5y2) * (9 + y)
3(28(9 + y) + -39y * (9 + y) + 5y2 * (9 + y)) = 0
3((9 * 28 + y * 28) + -39y * (9 + y) + 5y2 * (9 + y)) = 0
3((252 + 28y) + -39y * (9 + y) + 5y2 * (9 + y)) = 0
3(252 + 28y + (9 * -39y + y * -39y) + 5y2 * (9 + y)) = 0
3(252 + 28y + (-351y + -39y2) + 5y2 * (9 + y)) = 0
3(252 + 28y + -351y + -39y2 + (9 * 5y2 + y * 5y2)) = 0
3(252 + 28y + -351y + -39y2 + (45y2 + 5y3)) = 0

Combine like terms: 28y + -351y = -323y
3(252 + -323y + -39y2 + 45y2 + 5y3) = 0
