Simplifying (2w + 3)(7 + w) = 0 Reorder the terms: (3 + 2w)(7 + w) = 0 Multiply (3 + 2w) * (7 + w) (3(7 + w) + 2w * (7 + w)) = 0 ((7 * 3 + w * 3) + 2w * (7 + w)) = 0 ((21 + 3w) + 2w * (7 + w)) = 0 (21 + 3w + (7 * 2w + w * 2w)) = 0 (21 + 3w + (14w + 2w2)) = 0 Combine like terms: 3w + 14w = 17w (21 + 17w + 2w2) = 0 Solving 21 + 17w + 2w2 = 0 Solving for variable 'w'. Factor a trinomial. (7 + w)(3 + 2w) = 0Subproblem 1
Set the factor '(7 + w)' equal to zero and attempt to solve: Simplifying 7 + w = 0 Solving 7 + w = 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 + w = 0 + -7 Combine like terms: 7 + -7 = 0 0 + w = 0 + -7 w = 0 + -7 Combine like terms: 0 + -7 = -7 w = -7 Simplifying w = -7Subproblem 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 = {-7, -1.5}
