Solution for (y-1)(y-8)=0 equation:


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

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

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

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

Combine like terms: -1y + -8y = -9y
(8 + -9y + y2) = 0

Solving
8 + -9y + y2 = 0

Solving for variable 'y'.
