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

Solution for (1+y)(5y-6)=0 equation:

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

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

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

Combine like terms: 5y + -6y = -1y
(-6 + -1y + 5y2) = 0

Solving
-6 + -1y + 5y2 = 0

Solving for variable 'y'.
