Simplifying w2 = 6w + -18 Reorder the terms: w2 = -18 + 6w Solving w2 = -18 + 6w Solving for variable 'w'. Reorder the terms: 18 + -6w + w2 = -18 + 6w + 18 + -6w Reorder the terms: 18 + -6w + w2 = -18 + 18 + 6w + -6w Combine like terms: -18 + 18 = 0 18 + -6w + w2 = 0 + 6w + -6w 18 + -6w + w2 = 6w + -6w Combine like terms: 6w + -6w = 0 18 + -6w + w2 = 0 Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + -6w + -18 + w2 = 0 + -18 Reorder the terms: 18 + -18 + -6w + w2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + -6w + w2 = 0 + -18 -6w + w2 = 0 + -18 Combine like terms: 0 + -18 = -18 -6w + w2 = -18 The w term is -6w. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6w + 9 + w2 = -18 + 9 Reorder the terms: 9 + -6w + w2 = -18 + 9 Combine like terms: -18 + 9 = -9 9 + -6w + w2 = -9 Factor a perfect square on the left side: (w + -3)(w + -3) = -9 Can't calculate square root of the right side. The solution to this equation could not be determined.
