Solution for (3y+1)(y-5)=0 equation:


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

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

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

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

Combine like terms: 1y + -15y = -14y
(-5 + -14y + 3y2) = 0

Solving
-5 + -14y + 3y2 = 0
