Simplifying (2x2) + -5x + 6x + 15 = 0 Reorder the terms: 15 + -5x + 6x + (2x2) = 0 Combine like terms: -5x + 6x = 1x 15 + 1x + (2x2) = 0 Solving 15 + 1x + (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'. 7.5 + 0.5x + x2 = 0 Move the constant term to the right: Add '-7.5' to each side of the equation. 7.5 + 0.5x + -7.5 + x2 = 0 + -7.5 Reorder the terms: 7.5 + -7.5 + 0.5x + x2 = 0 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + 0.5x + x2 = 0 + -7.5 0.5x + x2 = 0 + -7.5 Combine like terms: 0 + -7.5 = -7.5 0.5x + x2 = -7.5 The x term is 0.5x. Take half its coefficient (0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. 0.5x + 0.0625 + x2 = -7.5 + 0.0625 Reorder the terms: 0.0625 + 0.5x + x2 = -7.5 + 0.0625 Combine like terms: -7.5 + 0.0625 = -7.4375 0.0625 + 0.5x + x2 = -7.4375 Factor a perfect square on the left side: ((x) + 0.25)((x) + 0.25) = -7.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
