Solution for (4y-5)(3-y)=0 equation:


Simplifying
(4y + -5)(3 + -1y) = 0

Reorder the terms:
(-5 + 4y)(3 + -1y) = 0

Multiply (-5 + 4y) * (3 + -1y)
(-5(3 + -1y) + 4y * (3 + -1y)) = 0
((3 * -5 + -1y * -5) + 4y * (3 + -1y)) = 0
((-15 + 5y) + 4y * (3 + -1y)) = 0
(-15 + 5y + (3 * 4y + -1y * 4y)) = 0
(-15 + 5y + (12y + -4y2)) = 0

Combine like terms: 5y + 12y = 17y
(-15 + 17y + -4y2) = 0
