Simplifying (w2 + -4w + -21)(9w + -18) = 0 Reorder the terms: (-21 + -4w + w2)(9w + -18) = 0 Reorder the terms: (-21 + -4w + w2)(-18 + 9w) = 0 Multiply (-21 + -4w + w2) * (-18 + 9w) (-21(-18 + 9w) + -4w * (-18 + 9w) + w2(-18 + 9w)) = 0 ((-18 * -21 + 9w * -21) + -4w * (-18 + 9w) + w2(-18 + 9w)) = 0 ((378 + -189w) + -4w * (-18 + 9w) + w2(-18 + 9w)) = 0 (378 + -189w + (-18 * -4w + 9w * -4w) + w2(-18 + 9w)) = 0 (378 + -189w + (72w + -36w2) + w2(-18 + 9w)) = 0 (378 + -189w + 72w + -36w2 + (-18 * w2 + 9w * w2)) = 0 (378 + -189w + 72w + -36w2 + (-18w2 + 9w3)) = 0 Combine like terms: -189w + 72w = -117w (378 + -117w + -36w2 + -18w2 + 9w3) = 0 Combine like terms: -36w2 + -18w2 = -54w2 (378 + -117w + -54w2 + 9w3) = 0 Solving 378 + -117w + -54w2 + 9w3 = 0 Solving for variable 'w'. Factor out the Greatest Common Factor (GCF), '9'. 9(42 + -13w + -6w2 + w3) = 0 Ignore the factor 9.Subproblem 1
Set the factor '(42 + -13w + -6w2 + w3)' equal to zero and attempt to solve: Simplifying 42 + -13w + -6w2 + w3 = 0 Solving 42 + -13w + -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.
