Simplifying x2 + -1x + -84 = 0 Reorder the terms: -84 + -1x + x2 = 0 Solving -84 + -1x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '84' to each side of the equation. -84 + -1x + 84 + x2 = 0 + 84 Reorder the terms: -84 + 84 + -1x + x2 = 0 + 84 Combine like terms: -84 + 84 = 0 0 + -1x + x2 = 0 + 84 -1x + x2 = 0 + 84 Combine like terms: 0 + 84 = 84 -1x + x2 = 84 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 = 84 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 84 + 0.25 Combine like terms: 84 + 0.25 = 84.25 0.25 + -1x + x2 = 84.25 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 84.25 Calculate the square root of the right side: 9.178779875 Break this problem into two subproblems by setting (x + -0.5) equal to 9.178779875 and -9.178779875.Subproblem 1
x + -0.5 = 9.178779875 Simplifying x + -0.5 = 9.178779875 Reorder the terms: -0.5 + x = 9.178779875 Solving -0.5 + x = 9.178779875 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 = 9.178779875 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 9.178779875 + 0.5 x = 9.178779875 + 0.5 Combine like terms: 9.178779875 + 0.5 = 9.678779875 x = 9.678779875 Simplifying x = 9.678779875Subproblem 2
x + -0.5 = -9.178779875 Simplifying x + -0.5 = -9.178779875 Reorder the terms: -0.5 + x = -9.178779875 Solving -0.5 + x = -9.178779875 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 = -9.178779875 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -9.178779875 + 0.5 x = -9.178779875 + 0.5 Combine like terms: -9.178779875 + 0.5 = -8.678779875 x = -8.678779875 Simplifying x = -8.678779875Solution
