Simplifying 2x2 + 17x + 130 = 0 Reorder the terms: 130 + 17x + 2x2 = 0 Solving 130 + 17x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 65 + 8.5x + x2 = 0 Move the constant term to the right: Add '-65' to each side of the equation. 65 + 8.5x + -65 + x2 = 0 + -65 Reorder the terms: 65 + -65 + 8.5x + x2 = 0 + -65 Combine like terms: 65 + -65 = 0 0 + 8.5x + x2 = 0 + -65 8.5x + x2 = 0 + -65 Combine like terms: 0 + -65 = -65 8.5x + x2 = -65 The x term is 8.5x. Take half its coefficient (4.25). Square it (18.0625) and add it to both sides. Add '18.0625' to each side of the equation. 8.5x + 18.0625 + x2 = -65 + 18.0625 Reorder the terms: 18.0625 + 8.5x + x2 = -65 + 18.0625 Combine like terms: -65 + 18.0625 = -46.9375 18.0625 + 8.5x + x2 = -46.9375 Factor a perfect square on the left side: (x + 4.25)(x + 4.25) = -46.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
