Simplifying 2w2 = -7w + 15 Reorder the terms: 2w2 = 15 + -7w Solving 2w2 = 15 + -7w Solving for variable 'w'. Reorder the terms: -15 + 7w + 2w2 = 15 + -7w + -15 + 7w Reorder the terms: -15 + 7w + 2w2 = 15 + -15 + -7w + 7w Combine like terms: 15 + -15 = 0 -15 + 7w + 2w2 = 0 + -7w + 7w -15 + 7w + 2w2 = -7w + 7w Combine like terms: -7w + 7w = 0 -15 + 7w + 2w2 = 0 Factor a trinomial. (-5 + -1w)(3 + -2w) = 0Subproblem 1
Set the factor '(-5 + -1w)' equal to zero and attempt to solve: Simplifying -5 + -1w = 0 Solving -5 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + -1w = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -1w = 0 + 5 -1w = 0 + 5 Combine like terms: 0 + 5 = 5 -1w = 5 Divide each side by '-1'. w = -5 Simplifying w = -5Subproblem 2
Set the factor '(3 + -2w)' equal to zero and attempt to solve: Simplifying 3 + -2w = 0 Solving 3 + -2w = 0 Move all terms containing w to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -2w = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -2w = 0 + -3 -2w = 0 + -3 Combine like terms: 0 + -3 = -3 -2w = -3 Divide each side by '-2'. w = 1.5 Simplifying w = 1.5Solution
w = {-5, 1.5}
