Solution for 2w(w+7)(w-1)=0 equation: 


Simplifying
2w(w + 7)(w + -1) = 0

Reorder the terms:
2w(7 + w)(w + -1) = 0

Reorder the terms:
2w(7 + w)(-1 + w) = 0

Multiply (7 + w) * (-1 + w)
2w(7(-1 + w) + w(-1 + w)) = 0
2w((-1 * 7 + w * 7) + w(-1 + w)) = 0
2w((-7 + 7w) + w(-1 + w)) = 0
2w(-7 + 7w + (-1 * w + w * w)) = 0
2w(-7 + 7w + (-1w + w2)) = 0

Combine like terms: 7w + -1w = 6w
2w(-7 + 6w + w2) = 0
(-7 * 2w + 6w * 2w + w2 * 2w) = 0
(-14w + 12w2 + 2w3) = 0

Solving
-14w + 12w2 + 2w3 = 0

Solving for variable 'w'.
