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

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

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

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

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

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

Solving
-48 + 22y + 5y2 = 0

Solving for variable 'y'.
