Simplifying 8x2 + -12x + -14 = -9 Reorder the terms: -14 + -12x + 8x2 = -9 Solving -14 + -12x + 8x2 = -9 Solving for variable 'x'. Reorder the terms: -14 + 9 + -12x + 8x2 = -9 + 9 Combine like terms: -14 + 9 = -5 -5 + -12x + 8x2 = -9 + 9 Combine like terms: -9 + 9 = 0 -5 + -12x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -0.625 + -1.5x + x2 = 0 Move the constant term to the right: Add '0.625' to each side of the equation. -0.625 + -1.5x + 0.625 + x2 = 0 + 0.625 Reorder the terms: -0.625 + 0.625 + -1.5x + x2 = 0 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + -1.5x + x2 = 0 + 0.625 -1.5x + x2 = 0 + 0.625 Combine like terms: 0 + 0.625 = 0.625 -1.5x + x2 = 0.625 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 = 0.625 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 0.625 + 0.5625 Combine like terms: 0.625 + 0.5625 = 1.1875 0.5625 + -1.5x + x2 = 1.1875 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 1.1875 Calculate the square root of the right side: 1.089724736 Break this problem into two subproblems by setting (x + -0.75) equal to 1.089724736 and -1.089724736.Subproblem 1
x + -0.75 = 1.089724736 Simplifying x + -0.75 = 1.089724736 Reorder the terms: -0.75 + x = 1.089724736 Solving -0.75 + x = 1.089724736 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 1.089724736 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 1.089724736 + 0.75 x = 1.089724736 + 0.75 Combine like terms: 1.089724736 + 0.75 = 1.839724736 x = 1.839724736 Simplifying x = 1.839724736Subproblem 2
x + -0.75 = -1.089724736 Simplifying x + -0.75 = -1.089724736 Reorder the terms: -0.75 + x = -1.089724736 Solving -0.75 + x = -1.089724736 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -1.089724736 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -1.089724736 + 0.75 x = -1.089724736 + 0.75 Combine like terms: -1.089724736 + 0.75 = -0.339724736 x = -0.339724736 Simplifying x = -0.339724736Solution
