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


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

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

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

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

Combine like terms: 2y + -15y = -13y
(-10 + -13y + 3y2) = 0

Solving
-10 + -13y + 3y2 = 0
