Simplifying (w + 7)(2w + -2)(w) = 1680 Reorder the terms: (7 + w)(2w + -2)(w) = 1680 Reorder the terms: (7 + w)(-2 + 2w)(w) = 1680 Reorder the terms for easier multiplication: w(7 + w)(-2 + 2w) = 1680 Multiply (7 + w) * (-2 + 2w) w(7(-2 + 2w) + w(-2 + 2w)) = 1680 w((-2 * 7 + 2w * 7) + w(-2 + 2w)) = 1680 w((-14 + 14w) + w(-2 + 2w)) = 1680 w(-14 + 14w + (-2 * w + 2w * w)) = 1680 w(-14 + 14w + (-2w + 2w2)) = 1680 Combine like terms: 14w + -2w = 12w w(-14 + 12w + 2w2) = 1680 (-14 * w + 12w * w + 2w2 * w) = 1680 (-14w + 12w2 + 2w3) = 1680 Solving -14w + 12w2 + 2w3 = 1680 Solving for variable 'w'. Reorder the terms: -1680 + -14w + 12w2 + 2w3 = 1680 + -1680 Combine like terms: 1680 + -1680 = 0 -1680 + -14w + 12w2 + 2w3 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-840 + -7w + 6w2 + w3) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-840 + -7w + 6w2 + w3)' equal to zero and attempt to solve: Simplifying -840 + -7w + 6w2 + w3 = 0 Solving -840 + -7w + 6w2 + w3 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
