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

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

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

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

Multiply (-5 + 3y) * (3 + -1y)
(-5(3 + -1y) + 3y * (3 + -1y)) = 0
((3 * -5 + -1y * -5) + 3y * (3 + -1y)) = 0
((-15 + 5y) + 3y * (3 + -1y)) = 0
(-15 + 5y + (3 * 3y + -1y * 3y)) = 0
(-15 + 5y + (9y + -3y2)) = 0

Combine like terms: 5y + 9y = 14y
(-15 + 14y + -3y2) = 0

Solving
-15 + 14y + -3y2 = 0

Solving for variable 'y'.
