Simplifying 8x2 + -2x + -18 = 15 Reorder the terms: -18 + -2x + 8x2 = 15 Solving -18 + -2x + 8x2 = 15 Solving for variable 'x'. Reorder the terms: -18 + -15 + -2x + 8x2 = 15 + -15 Combine like terms: -18 + -15 = -33 -33 + -2x + 8x2 = 15 + -15 Combine like terms: 15 + -15 = 0 -33 + -2x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -4.125 + -0.25x + x2 = 0 Move the constant term to the right: Add '4.125' to each side of the equation. -4.125 + -0.25x + 4.125 + x2 = 0 + 4.125 Reorder the terms: -4.125 + 4.125 + -0.25x + x2 = 0 + 4.125 Combine like terms: -4.125 + 4.125 = 0.000 0.000 + -0.25x + x2 = 0 + 4.125 -0.25x + x2 = 0 + 4.125 Combine like terms: 0 + 4.125 = 4.125 -0.25x + x2 = 4.125 The x term is -0.25x. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25x + 0.015625 + x2 = 4.125 + 0.015625 Reorder the terms: 0.015625 + -0.25x + x2 = 4.125 + 0.015625 Combine like terms: 4.125 + 0.015625 = 4.140625 0.015625 + -0.25x + x2 = 4.140625 Factor a perfect square on the left side: (x + -0.125)(x + -0.125) = 4.140625 Calculate the square root of the right side: 2.034852575 Break this problem into two subproblems by setting (x + -0.125) equal to 2.034852575 and -2.034852575.Subproblem 1
x + -0.125 = 2.034852575 Simplifying x + -0.125 = 2.034852575 Reorder the terms: -0.125 + x = 2.034852575 Solving -0.125 + x = 2.034852575 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + x = 2.034852575 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = 2.034852575 + 0.125 x = 2.034852575 + 0.125 Combine like terms: 2.034852575 + 0.125 = 2.159852575 x = 2.159852575 Simplifying x = 2.159852575Subproblem 2
x + -0.125 = -2.034852575 Simplifying x + -0.125 = -2.034852575 Reorder the terms: -0.125 + x = -2.034852575 Solving -0.125 + x = -2.034852575 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + x = -2.034852575 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = -2.034852575 + 0.125 x = -2.034852575 + 0.125 Combine like terms: -2.034852575 + 0.125 = -1.909852575 x = -1.909852575 Simplifying x = -1.909852575Solution
