(6-y)(5y+3)=0

Solution for (6-y)(5y+3)=0 equation:

Simplifying
(6 + -1y)(5y + 3) = 0

Reorder the terms:
(6 + -1y)(3 + 5y) = 0

Multiply (6 + -1y) * (3 + 5y)
(6(3 + 5y) + -1y * (3 + 5y)) = 0
((3 * 6 + 5y * 6) + -1y * (3 + 5y)) = 0
((18 + 30y) + -1y * (3 + 5y)) = 0
(18 + 30y + (3 * -1y + 5y * -1y)) = 0
(18 + 30y + (-3y + -5y2)) = 0

Combine like terms: 30y + -3y = 27y
(18 + 27y + -5y2) = 0

Solving
18 + 27y + -5y2 = 0
