Simplifying 4w * w + 21w = -5 Multiply w * w 4w2 + 21w = -5 Reorder the terms: 21w + 4w2 = -5 Solving 21w + 4w2 = -5 Solving for variable 'w'. Reorder the terms: 5 + 21w + 4w2 = -5 + 5 Combine like terms: -5 + 5 = 0 5 + 21w + 4w2 = 0 Factor a trinomial. (5 + w)(1 + 4w) = 0Subproblem 1
Set the factor '(5 + w)' equal to zero and attempt to solve: Simplifying 5 + w = 0 Solving 5 + w = 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 + w = 0 + -5 Combine like terms: 5 + -5 = 0 0 + w = 0 + -5 w = 0 + -5 Combine like terms: 0 + -5 = -5 w = -5 Simplifying w = -5Subproblem 2
Set the factor '(1 + 4w)' equal to zero and attempt to solve: Simplifying 1 + 4w = 0 Solving 1 + 4w = 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 + 4w = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 4w = 0 + -1 4w = 0 + -1 Combine like terms: 0 + -1 = -1 4w = -1 Divide each side by '4'. w = -0.25 Simplifying w = -0.25Solution
w = {-5, -0.25}
