Simplifying (2w + -7)(1 + w) = 0 Reorder the terms: (-7 + 2w)(1 + w) = 0 Multiply (-7 + 2w) * (1 + w) (-7(1 + w) + 2w * (1 + w)) = 0 ((1 * -7 + w * -7) + 2w * (1 + w)) = 0 ((-7 + -7w) + 2w * (1 + w)) = 0 (-7 + -7w + (1 * 2w + w * 2w)) = 0 (-7 + -7w + (2w + 2w2)) = 0 Combine like terms: -7w + 2w = -5w (-7 + -5w + 2w2) = 0 Solving -7 + -5w + 2w2 = 0 Solving for variable 'w'. Factor a trinomial. (-1 + -1w)(7 + -2w) = 0Subproblem 1
Set the factor '(-1 + -1w)' equal to zero and attempt to solve: Simplifying -1 + -1w = 0 Solving -1 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + -1w = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1w = 0 + 1 -1w = 0 + 1 Combine like terms: 0 + 1 = 1 -1w = 1 Divide each side by '-1'. w = -1 Simplifying w = -1Subproblem 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 = {-1, 3.5}
