Solution for w(7+w)(w-2)=1680 equation:


Simplifying
w(7 + w)(w + -2) = 1680

Reorder the terms:
w(7 + w)(-2 + w) = 1680

Multiply (7 + w) * (-2 + w)
w(7(-2 + w) + w(-2 + w)) = 1680
w((-2 * 7 + w * 7) + w(-2 + w)) = 1680
w((-14 + 7w) + w(-2 + w)) = 1680
w(-14 + 7w + (-2 * w + w * w)) = 1680
w(-14 + 7w + (-2w + w2)) = 1680

Combine like terms: 7w + -2w = 5w
w(-14 + 5w + w2) = 1680
(-14 * w + 5w * w + w2 * w) = 1680
(-14w + 5w2 + w3) = 1680

Solving
-14w + 5w2 + w3 = 1680

Solving for variable 'w'.

Reorder the terms:
-1680 + -14w + 5w2 + w3 = 1680 + -1680

Combine like terms: 1680 + -1680 = 0
-1680 + -14w + 5w2 + w3 = 0

The solution to this equation could not be determined.
