Solution for (w+8)(w-2)=0 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
