Solution for (y+8)(y-1)= equation: 


Simplifying
(y + 8)(y + -1) = 0

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

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

Multiply (8 + y) * (-1 + y)
(8(-1 + y) + y(-1 + y)) = 0
((-1 * 8 + y * 8) + y(-1 + y)) = 0
((-8 + 8y) + y(-1 + y)) = 0
(-8 + 8y + (-1 * y + y * y)) = 0
(-8 + 8y + (-1y + y2)) = 0
