Simplifying x2 + -18x + -25 = 96 Reorder the terms: -25 + -18x + x2 = 96 Solving -25 + -18x + x2 = 96 Solving for variable 'x'. Reorder the terms: -25 + -96 + -18x + x2 = 96 + -96 Combine like terms: -25 + -96 = -121 -121 + -18x + x2 = 96 + -96 Combine like terms: 96 + -96 = 0 -121 + -18x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '121' to each side of the equation. -121 + -18x + 121 + x2 = 0 + 121 Reorder the terms: -121 + 121 + -18x + x2 = 0 + 121 Combine like terms: -121 + 121 = 0 0 + -18x + x2 = 0 + 121 -18x + x2 = 0 + 121 Combine like terms: 0 + 121 = 121 -18x + x2 = 121 The x term is -18x. Take half its coefficient (-9). Square it (81) and add it to both sides. Add '81' to each side of the equation. -18x + 81 + x2 = 121 + 81 Reorder the terms: 81 + -18x + x2 = 121 + 81 Combine like terms: 121 + 81 = 202 81 + -18x + x2 = 202 Factor a perfect square on the left side: (x + -9)(x + -9) = 202 Calculate the square root of the right side: 14.212670404 Break this problem into two subproblems by setting (x + -9) equal to 14.212670404 and -14.212670404.Subproblem 1
x + -9 = 14.212670404 Simplifying x + -9 = 14.212670404 Reorder the terms: -9 + x = 14.212670404 Solving -9 + x = 14.212670404 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + x = 14.212670404 + 9 Combine like terms: -9 + 9 = 0 0 + x = 14.212670404 + 9 x = 14.212670404 + 9 Combine like terms: 14.212670404 + 9 = 23.212670404 x = 23.212670404 Simplifying x = 23.212670404Subproblem 2
x + -9 = -14.212670404 Simplifying x + -9 = -14.212670404 Reorder the terms: -9 + x = -14.212670404 Solving -9 + x = -14.212670404 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + x = -14.212670404 + 9 Combine like terms: -9 + 9 = 0 0 + x = -14.212670404 + 9 x = -14.212670404 + 9 Combine like terms: -14.212670404 + 9 = -5.212670404 x = -5.212670404 Simplifying x = -5.212670404Solution
