Simplifying 2x2 + -1x + 78 = 0 Reorder the terms: 78 + -1x + 2x2 = 0 Solving 78 + -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'. 39 + -0.5x + x2 = 0 Move the constant term to the right: Add '-39' to each side of the equation. 39 + -0.5x + -39 + x2 = 0 + -39 Reorder the terms: 39 + -39 + -0.5x + x2 = 0 + -39 Combine like terms: 39 + -39 = 0 0 + -0.5x + x2 = 0 + -39 -0.5x + x2 = 0 + -39 Combine like terms: 0 + -39 = -39 -0.5x + x2 = -39 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 = -39 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = -39 + 0.0625 Combine like terms: -39 + 0.0625 = -38.9375 0.0625 + -0.5x + x2 = -38.9375 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = -38.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
