Simplifying -8x2 + 11x + 56 = 0 Reorder the terms: 56 + 11x + -8x2 = 0 Solving 56 + 11x + -8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. -7 + -1.375x + x2 = 0 Move the constant term to the right: Add '7' to each side of the equation. -7 + -1.375x + 7 + x2 = 0 + 7 Reorder the terms: -7 + 7 + -1.375x + x2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -1.375x + x2 = 0 + 7 -1.375x + x2 = 0 + 7 Combine like terms: 0 + 7 = 7 -1.375x + x2 = 7 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 = 7 + 0.47265625 Reorder the terms: 0.47265625 + -1.375x + x2 = 7 + 0.47265625 Combine like terms: 7 + 0.47265625 = 7.47265625 0.47265625 + -1.375x + x2 = 7.47265625 Factor a perfect square on the left side: (x + -0.6875)(x + -0.6875) = 7.47265625 Calculate the square root of the right side: 2.733615966 Break this problem into two subproblems by setting (x + -0.6875) equal to 2.733615966 and -2.733615966.Subproblem 1
x + -0.6875 = 2.733615966 Simplifying x + -0.6875 = 2.733615966 Reorder the terms: -0.6875 + x = 2.733615966 Solving -0.6875 + x = 2.733615966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.6875' to each side of the equation. -0.6875 + 0.6875 + x = 2.733615966 + 0.6875 Combine like terms: -0.6875 + 0.6875 = 0.0000 0.0000 + x = 2.733615966 + 0.6875 x = 2.733615966 + 0.6875 Combine like terms: 2.733615966 + 0.6875 = 3.421115966 x = 3.421115966 Simplifying x = 3.421115966Subproblem 2
x + -0.6875 = -2.733615966 Simplifying x + -0.6875 = -2.733615966 Reorder the terms: -0.6875 + x = -2.733615966 Solving -0.6875 + x = -2.733615966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
