Simplifying (4w + 7)(1 + w) = 0 Reorder the terms: (7 + 4w)(1 + w) = 0 Multiply (7 + 4w) * (1 + w) (7(1 + w) + 4w * (1 + w)) = 0 ((1 * 7 + w * 7) + 4w * (1 + w)) = 0 ((7 + 7w) + 4w * (1 + w)) = 0 (7 + 7w + (1 * 4w + w * 4w)) = 0 (7 + 7w + (4w + 4w2)) = 0 Combine like terms: 7w + 4w = 11w (7 + 11w + 4w2) = 0 Solving 7 + 11w + 4w2 = 0 Solving for variable 'w'. Factor a trinomial. (7 + 4w)(1 + w) = 0Subproblem 1
Set the factor '(7 + 4w)' equal to zero and attempt to solve: Simplifying 7 + 4w = 0 Solving 7 + 4w = 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 + 4w = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 4w = 0 + -7 4w = 0 + -7 Combine like terms: 0 + -7 = -7 4w = -7 Divide each side by '4'. w = -1.75 Simplifying w = -1.75Subproblem 2
Set the factor '(1 + w)' equal to zero and attempt to solve: Simplifying 1 + w = 0 Solving 1 + w = 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 + w = 0 + -1 Combine like terms: 1 + -1 = 0 0 + w = 0 + -1 w = 0 + -1 Combine like terms: 0 + -1 = -1 w = -1 Simplifying w = -1Solution
w = {-1.75, -1}
