(5y+8)(6-y)=0

Solution for (5y+8)(6-y)=0 equation:

Simplifying
(5y + 8)(6 + -1y) = 0

Reorder the terms:
(8 + 5y)(6 + -1y) = 0

Multiply (8 + 5y) * (6 + -1y)
(8(6 + -1y) + 5y * (6 + -1y)) = 0
((6 * 8 + -1y * 8) + 5y * (6 + -1y)) = 0
((48 + -8y) + 5y * (6 + -1y)) = 0
(48 + -8y + (6 * 5y + -1y * 5y)) = 0
(48 + -8y + (30y + -5y2)) = 0

Combine like terms: -8y + 30y = 22y
(48 + 22y + -5y2) = 0

Solving
