(2y-3)(y+5)=0

Solution for (2y-3)(y+5)=0 equation:

Simplifying
(2y + -3)(y + 5) = 0

Reorder the terms:
(-3 + 2y)(y + 5) = 0

Reorder the terms:
(-3 + 2y)(5 + y) = 0

Multiply (-3 + 2y) * (5 + y)
(-3(5 + y) + 2y * (5 + y)) = 0
((5 * -3 + y * -3) + 2y * (5 + y)) = 0
((-15 + -3y) + 2y * (5 + y)) = 0
(-15 + -3y + (5 * 2y + y * 2y)) = 0
(-15 + -3y + (10y + 2y2)) = 0

Combine like terms: -3y + 10y = 7y
(-15 + 7y + 2y2) = 0

Solving
-15 + 7y + 2y2 = 0

Solving for variable 'y'.
