Simplifying -7w(w + -1) = -5 + 9 Reorder the terms: -7w(-1 + w) = -5 + 9 (-1 * -7w + w * -7w) = -5 + 9 (7w + -7w2) = -5 + 9 Combine like terms: -5 + 9 = 4 7w + -7w2 = 4 Solving 7w + -7w2 = 4 Solving for variable 'w'. Reorder the terms: -4 + 7w + -7w2 = 4 + -4 Combine like terms: 4 + -4 = 0 -4 + 7w + -7w2 = 0 Begin completing the square. Divide all terms by -7 the coefficient of the squared term: Divide each side by '-7'. 0.5714285714 + -1w + w2 = 0 Move the constant term to the right: Add '-0.5714285714' to each side of the equation. 0.5714285714 + -1w + -0.5714285714 + w2 = 0 + -0.5714285714 Reorder the terms: 0.5714285714 + -0.5714285714 + -1w + w2 = 0 + -0.5714285714 Combine like terms: 0.5714285714 + -0.5714285714 = 0.0000000000 0.0000000000 + -1w + w2 = 0 + -0.5714285714 -1w + w2 = 0 + -0.5714285714 Combine like terms: 0 + -0.5714285714 = -0.5714285714 -1w + w2 = -0.5714285714 The w term is -1w. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1w + 0.25 + w2 = -0.5714285714 + 0.25 Reorder the terms: 0.25 + -1w + w2 = -0.5714285714 + 0.25 Combine like terms: -0.5714285714 + 0.25 = -0.3214285714 0.25 + -1w + w2 = -0.3214285714 Factor a perfect square on the left side: (w + -0.5)(w + -0.5) = -0.3214285714 Can't calculate square root of the right side. The solution to this equation could not be determined.
