Simplifying (2w + 7)(3 + -1w) = 0 Reorder the terms: (7 + 2w)(3 + -1w) = 0 Multiply (7 + 2w) * (3 + -1w) (7(3 + -1w) + 2w * (3 + -1w)) = 0 ((3 * 7 + -1w * 7) + 2w * (3 + -1w)) = 0 ((21 + -7w) + 2w * (3 + -1w)) = 0 (21 + -7w + (3 * 2w + -1w * 2w)) = 0 (21 + -7w + (6w + -2w2)) = 0 Combine like terms: -7w + 6w = -1w (21 + -1w + -2w2) = 0 Solving 21 + -1w + -2w2 = 0 Solving for variable 'w'. Factor a trinomial. (3 + -1w)(7 + 2w) = 0Subproblem 1
Set the factor '(3 + -1w)' equal to zero and attempt to solve: Simplifying 3 + -1w = 0 Solving 3 + -1w = 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 + -1w = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1w = 0 + -3 -1w = 0 + -3 Combine like terms: 0 + -3 = -3 -1w = -3 Divide each side by '-1'. w = 3 Simplifying w = 3Subproblem 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 = {3, -3.5}
