Simplifying x2 + -18x + 11 = 0 Reorder the terms: 11 + -18x + x2 = 0 Solving 11 + -18x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-11' to each side of the equation. 11 + -18x + -11 + x2 = 0 + -11 Reorder the terms: 11 + -11 + -18x + x2 = 0 + -11 Combine like terms: 11 + -11 = 0 0 + -18x + x2 = 0 + -11 -18x + x2 = 0 + -11 Combine like terms: 0 + -11 = -11 -18x + x2 = -11 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 = -11 + 81 Reorder the terms: 81 + -18x + x2 = -11 + 81 Combine like terms: -11 + 81 = 70 81 + -18x + x2 = 70 Factor a perfect square on the left side: (x + -9)(x + -9) = 70 Calculate the square root of the right side: 8.366600265 Break this problem into two subproblems by setting (x + -9) equal to 8.366600265 and -8.366600265.Subproblem 1
x + -9 = 8.366600265 Simplifying x + -9 = 8.366600265 Reorder the terms: -9 + x = 8.366600265 Solving -9 + x = 8.366600265 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 = 8.366600265 + 9 Combine like terms: -9 + 9 = 0 0 + x = 8.366600265 + 9 x = 8.366600265 + 9 Combine like terms: 8.366600265 + 9 = 17.366600265 x = 17.366600265 Simplifying x = 17.366600265Subproblem 2
x + -9 = -8.366600265 Simplifying x + -9 = -8.366600265 Reorder the terms: -9 + x = -8.366600265 Solving -9 + x = -8.366600265 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 = -8.366600265 + 9 Combine like terms: -9 + 9 = 0 0 + x = -8.366600265 + 9 x = -8.366600265 + 9 Combine like terms: -8.366600265 + 9 = 0.633399735 x = 0.633399735 Simplifying x = 0.633399735Solution
The solution to the problem is based on the solutions from the subproblems. x = {17.366600265, 0.633399735}
