Solution for (2y+5)(y-4)= equation:


Simplifying
(2y + 5)(y + -4) = 0

Reorder the terms:
(5 + 2y)(y + -4) = 0

Reorder the terms:
(5 + 2y)(-4 + y) = 0

Multiply (5 + 2y) * (-4 + y)
(5(-4 + y) + 2y * (-4 + y)) = 0
((-4 * 5 + y * 5) + 2y * (-4 + y)) = 0
((-20 + 5y) + 2y * (-4 + y)) = 0
(-20 + 5y + (-4 * 2y + y * 2y)) = 0
(-20 + 5y + (-8y + 2y2)) = 0

Combine like terms: 5y + -8y = -3y
(-20 + -3y + 2y2) = 0

Solving
-20 + -3y + 2y2 = 0
