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


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

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

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

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

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

Solving
-16 + -6w + w2 = 0
