Simplifying -2x2 + 36 = -2x + 9 Reorder the terms: 36 + -2x2 = -2x + 9 Reorder the terms: 36 + -2x2 = 9 + -2x Solving 36 + -2x2 = 9 + -2x Solving for variable 'x'. Reorder the terms: 36 + -9 + 2x + -2x2 = 9 + -2x + -9 + 2x Combine like terms: 36 + -9 = 27 27 + 2x + -2x2 = 9 + -2x + -9 + 2x Reorder the terms: 27 + 2x + -2x2 = 9 + -9 + -2x + 2x Combine like terms: 9 + -9 = 0 27 + 2x + -2x2 = 0 + -2x + 2x 27 + 2x + -2x2 = -2x + 2x Combine like terms: -2x + 2x = 0 27 + 2x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -13.5 + -1x + x2 = 0 Move the constant term to the right: Add '13.5' to each side of the equation. -13.5 + -1x + 13.5 + x2 = 0 + 13.5 Reorder the terms: -13.5 + 13.5 + -1x + x2 = 0 + 13.5 Combine like terms: -13.5 + 13.5 = 0.0 0.0 + -1x + x2 = 0 + 13.5 -1x + x2 = 0 + 13.5 Combine like terms: 0 + 13.5 = 13.5 -1x + x2 = 13.5 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = 13.5 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 13.5 + 0.25 Combine like terms: 13.5 + 0.25 = 13.75 0.25 + -1x + x2 = 13.75 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 13.75 Calculate the square root of the right side: 3.708099244 Break this problem into two subproblems by setting (x + -0.5) equal to 3.708099244 and -3.708099244.Subproblem 1
x + -0.5 = 3.708099244 Simplifying x + -0.5 = 3.708099244 Reorder the terms: -0.5 + x = 3.708099244 Solving -0.5 + x = 3.708099244 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 3.708099244 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 3.708099244 + 0.5 x = 3.708099244 + 0.5 Combine like terms: 3.708099244 + 0.5 = 4.208099244 x = 4.208099244 Simplifying x = 4.208099244Subproblem 2
x + -0.5 = -3.708099244 Simplifying x + -0.5 = -3.708099244 Reorder the terms: -0.5 + x = -3.708099244 Solving -0.5 + x = -3.708099244 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -3.708099244 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -3.708099244 + 0.5 x = -3.708099244 + 0.5 Combine like terms: -3.708099244 + 0.5 = -3.208099244 x = -3.208099244 Simplifying x = -3.208099244Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.208099244, -3.208099244}
