Simplifying 4w2 = 15w + 4 Reorder the terms: 4w2 = 4 + 15w Solving 4w2 = 4 + 15w Solving for variable 'w'. Reorder the terms: -4 + -15w + 4w2 = 4 + 15w + -4 + -15w Reorder the terms: -4 + -15w + 4w2 = 4 + -4 + 15w + -15w Combine like terms: 4 + -4 = 0 -4 + -15w + 4w2 = 0 + 15w + -15w -4 + -15w + 4w2 = 15w + -15w Combine like terms: 15w + -15w = 0 -4 + -15w + 4w2 = 0 Factor a trinomial. (-1 + -4w)(4 + -1w) = 0Subproblem 1
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 = -0.25Subproblem 2
Set the factor '(4 + -1w)' equal to zero and attempt to solve: Simplifying 4 + -1w = 0 Solving 4 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1w = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1w = 0 + -4 -1w = 0 + -4 Combine like terms: 0 + -4 = -4 -1w = -4 Divide each side by '-1'. w = 4 Simplifying w = 4Solution
w = {-0.25, 4}
