Simplifying 2x2 + -4x + 8 = -1x + -4 Reorder the terms: 8 + -4x + 2x2 = -1x + -4 Reorder the terms: 8 + -4x + 2x2 = -4 + -1x Solving 8 + -4x + 2x2 = -4 + -1x Solving for variable 'x'. Reorder the terms: 8 + 4 + -4x + x + 2x2 = -4 + -1x + 4 + x Combine like terms: 8 + 4 = 12 12 + -4x + x + 2x2 = -4 + -1x + 4 + x Combine like terms: -4x + x = -3x 12 + -3x + 2x2 = -4 + -1x + 4 + x Reorder the terms: 12 + -3x + 2x2 = -4 + 4 + -1x + x Combine like terms: -4 + 4 = 0 12 + -3x + 2x2 = 0 + -1x + x 12 + -3x + 2x2 = -1x + x Combine like terms: -1x + x = 0 12 + -3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 6 + -1.5x + x2 = 0 Move the constant term to the right: Add '-6' to each side of the equation. 6 + -1.5x + -6 + x2 = 0 + -6 Reorder the terms: 6 + -6 + -1.5x + x2 = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1.5x + x2 = 0 + -6 -1.5x + x2 = 0 + -6 Combine like terms: 0 + -6 = -6 -1.5x + x2 = -6 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = -6 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = -6 + 0.5625 Combine like terms: -6 + 0.5625 = -5.4375 0.5625 + -1.5x + x2 = -5.4375 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = -5.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
