Solution for (w+2)*(w-8)= equation: 


Simplifying
(w + 2)(w + -8) = 0

Reorder the terms:
(2 + w)(w + -8) = 0

Reorder the terms:
(2 + w)(-8 + w) = 0

Multiply (2 + w) * (-8 + w)
(2(-8 + w) + w(-8 + w)) = 0
((-8 * 2 + w * 2) + w(-8 + w)) = 0
((-16 + 2w) + w(-8 + w)) = 0
(-16 + 2w + (-8 * w + w * w)) = 0
(-16 + 2w + (-8w + w2)) = 0

Combine like terms: 2w + -8w = -6w
(-16 + -6w + w2) = 0

Solving
-16 + -6w + w2 = 0

Solving for variable 'w'.
