Simplifying 0 = 2w2 + -7w Reorder the terms: 0 = -7w + 2w2 Solving 0 = -7w + 2w2 Solving for variable 'w'. Remove the zero: 7w + -2w2 = -7w + 2w2 + 7w + -2w2 Reorder the terms: 7w + -2w2 = -7w + 7w + 2w2 + -2w2 Combine like terms: -7w + 7w = 0 7w + -2w2 = 0 + 2w2 + -2w2 7w + -2w2 = 2w2 + -2w2 Combine like terms: 2w2 + -2w2 = 0 7w + -2w2 = 0 Factor out the Greatest Common Factor (GCF), 'w'. w(7 + -2w) = 0Subproblem 1
Set the factor 'w' equal to zero and attempt to solve: Simplifying w = 0 Solving w = 0 Move all terms containing w to the left, all other terms to the right. Simplifying w = 0Subproblem 2
Set the factor '(7 + -2w)' equal to zero and attempt to solve: Simplifying 7 + -2w = 0 Solving 7 + -2w = 0 Move all terms containing w to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -2w = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -2w = 0 + -7 -2w = 0 + -7 Combine like terms: 0 + -7 = -7 -2w = -7 Divide each side by '-2'. w = 3.5 Simplifying w = 3.5Solution
w = {0, 3.5}
