Simplifying 2x2 + -67x + 730 = 0 Reorder the terms: 730 + -67x + 2x2 = 0 Solving 730 + -67x + 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'. 365 + -33.5x + x2 = 0 Move the constant term to the right: Add '-365' to each side of the equation. 365 + -33.5x + -365 + x2 = 0 + -365 Reorder the terms: 365 + -365 + -33.5x + x2 = 0 + -365 Combine like terms: 365 + -365 = 0 0 + -33.5x + x2 = 0 + -365 -33.5x + x2 = 0 + -365 Combine like terms: 0 + -365 = -365 -33.5x + x2 = -365 The x term is -33.5x. Take half its coefficient (-16.75). Square it (280.5625) and add it to both sides. Add '280.5625' to each side of the equation. -33.5x + 280.5625 + x2 = -365 + 280.5625 Reorder the terms: 280.5625 + -33.5x + x2 = -365 + 280.5625 Combine like terms: -365 + 280.5625 = -84.4375 280.5625 + -33.5x + x2 = -84.4375 Factor a perfect square on the left side: (x + -16.75)(x + -16.75) = -84.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
