Simplifying 8x2 + 12x + -13 = 0 Reorder the terms: -13 + 12x + 8x2 = 0 Solving -13 + 12x + 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'. -1.625 + 1.5x + x2 = 0 Move the constant term to the right: Add '1.625' to each side of the equation. -1.625 + 1.5x + 1.625 + x2 = 0 + 1.625 Reorder the terms: -1.625 + 1.625 + 1.5x + x2 = 0 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + 1.5x + x2 = 0 + 1.625 1.5x + x2 = 0 + 1.625 Combine like terms: 0 + 1.625 = 1.625 1.5x + x2 = 1.625 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 = 1.625 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 1.625 + 0.5625 Combine like terms: 1.625 + 0.5625 = 2.1875 0.5625 + 1.5x + x2 = 2.1875 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 2.1875 Calculate the square root of the right side: 1.479019946 Break this problem into two subproblems by setting (x + 0.75) equal to 1.479019946 and -1.479019946.Subproblem 1
x + 0.75 = 1.479019946 Simplifying x + 0.75 = 1.479019946 Reorder the terms: 0.75 + x = 1.479019946 Solving 0.75 + x = 1.479019946 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 = 1.479019946 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = 1.479019946 + -0.75 x = 1.479019946 + -0.75 Combine like terms: 1.479019946 + -0.75 = 0.729019946 x = 0.729019946 Simplifying x = 0.729019946Subproblem 2
x + 0.75 = -1.479019946 Simplifying x + 0.75 = -1.479019946 Reorder the terms: 0.75 + x = -1.479019946 Solving 0.75 + x = -1.479019946 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 = -1.479019946 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = -1.479019946 + -0.75 x = -1.479019946 + -0.75 Combine like terms: -1.479019946 + -0.75 = -2.229019946 x = -2.229019946 Simplifying x = -2.229019946Solution
