Simplifying 5w2 + 20w + 20 = 0 Reorder the terms: 20 + 20w + 5w2 = 0 Solving 20 + 20w + 5w2 = 0 Solving for variable 'w'. Factor out the Greatest Common Factor (GCF), '5'. 5(4 + 4w + w2) = 0 Factor a trinomial. 5((2 + w)(2 + w)) = 0 Ignore the factor 5.Subproblem 1
Set the factor '(2 + w)' equal to zero and attempt to solve: Simplifying 2 + w = 0 Solving 2 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + w = 0 + -2 Combine like terms: 2 + -2 = 0 0 + w = 0 + -2 w = 0 + -2 Combine like terms: 0 + -2 = -2 w = -2 Simplifying w = -2Subproblem 2
