Simplifying 2w2 + 5w + 63 = 0 Reorder the terms: 63 + 5w + 2w2 = 0 Solving 63 + 5w + 2w2 = 0 Solving for variable 'w'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 31.5 + 2.5w + w2 = 0 Move the constant term to the right: Add '-31.5' to each side of the equation. 31.5 + 2.5w + -31.5 + w2 = 0 + -31.5 Reorder the terms: 31.5 + -31.5 + 2.5w + w2 = 0 + -31.5 Combine like terms: 31.5 + -31.5 = 0.0 0.0 + 2.5w + w2 = 0 + -31.5 2.5w + w2 = 0 + -31.5 Combine like terms: 0 + -31.5 = -31.5 2.5w + w2 = -31.5 The w term is 2.5w. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5w + 1.5625 + w2 = -31.5 + 1.5625 Reorder the terms: 1.5625 + 2.5w + w2 = -31.5 + 1.5625 Combine like terms: -31.5 + 1.5625 = -29.9375 1.5625 + 2.5w + w2 = -29.9375 Factor a perfect square on the left side: (w + 1.25)(w + 1.25) = -29.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
