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

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

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

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

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

Multiply (5 + -2y) * (3 + y)
(5(3 + y) + -2y * (3 + y)) = 0
((3 * 5 + y * 5) + -2y * (3 + y)) = 0
((15 + 5y) + -2y * (3 + y)) = 0
(15 + 5y + (3 * -2y + y * -2y)) = 0
(15 + 5y + (-6y + -2y2)) = 0
