Simplifying 8x2 = -11x + -7 Reorder the terms: 8x2 = -7 + -11x Solving 8x2 = -7 + -11x Solving for variable 'x'. Reorder the terms: 7 + 11x + 8x2 = -7 + -11x + 7 + 11x Reorder the terms: 7 + 11x + 8x2 = -7 + 7 + -11x + 11x Combine like terms: -7 + 7 = 0 7 + 11x + 8x2 = 0 + -11x + 11x 7 + 11x + 8x2 = -11x + 11x Combine like terms: -11x + 11x = 0 7 + 11x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.875 + 1.375x + x2 = 0 Move the constant term to the right: Add '-0.875' to each side of the equation. 0.875 + 1.375x + -0.875 + x2 = 0 + -0.875 Reorder the terms: 0.875 + -0.875 + 1.375x + x2 = 0 + -0.875 Combine like terms: 0.875 + -0.875 = 0.000 0.000 + 1.375x + x2 = 0 + -0.875 1.375x + x2 = 0 + -0.875 Combine like terms: 0 + -0.875 = -0.875 1.375x + x2 = -0.875 The x term is 1.375x. Take half its coefficient (0.6875). Square it (0.47265625) and add it to both sides. Add '0.47265625' to each side of the equation. 1.375x + 0.47265625 + x2 = -0.875 + 0.47265625 Reorder the terms: 0.47265625 + 1.375x + x2 = -0.875 + 0.47265625 Combine like terms: -0.875 + 0.47265625 = -0.40234375 0.47265625 + 1.375x + x2 = -0.40234375 Factor a perfect square on the left side: (x + 0.6875)(x + 0.6875) = -0.40234375 Can't calculate square root of the right side. The solution to this equation could not be determined.
