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

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

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

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

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

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

Solving
-5 + 14y + 3y2 = 0

Solving for variable 'y'.

Factor a trinomial.
