Simplifying x2 + -18x + -50 = 0 Reorder the terms: -50 + -18x + x2 = 0 Solving -50 + -18x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '50' to each side of the equation. -50 + -18x + 50 + x2 = 0 + 50 Reorder the terms: -50 + 50 + -18x + x2 = 0 + 50 Combine like terms: -50 + 50 = 0 0 + -18x + x2 = 0 + 50 -18x + x2 = 0 + 50 Combine like terms: 0 + 50 = 50 -18x + x2 = 50 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 = 50 + 81 Reorder the terms: 81 + -18x + x2 = 50 + 81 Combine like terms: 50 + 81 = 131 81 + -18x + x2 = 131 Factor a perfect square on the left side: (x + -9)(x + -9) = 131 Calculate the square root of the right side: 11.445523142 Break this problem into two subproblems by setting (x + -9) equal to 11.445523142 and -11.445523142.Subproblem 1
x + -9 = 11.445523142 Simplifying x + -9 = 11.445523142 Reorder the terms: -9 + x = 11.445523142 Solving -9 + x = 11.445523142 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 = 11.445523142 + 9 Combine like terms: -9 + 9 = 0 0 + x = 11.445523142 + 9 x = 11.445523142 + 9 Combine like terms: 11.445523142 + 9 = 20.445523142 x = 20.445523142 Simplifying x = 20.445523142Subproblem 2
x + -9 = -11.445523142 Simplifying x + -9 = -11.445523142 Reorder the terms: -9 + x = -11.445523142 Solving -9 + x = -11.445523142 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 = -11.445523142 + 9 Combine like terms: -9 + 9 = 0 0 + x = -11.445523142 + 9 x = -11.445523142 + 9 Combine like terms: -11.445523142 + 9 = -2.445523142 x = -2.445523142 Simplifying x = -2.445523142Solution
The solution to the problem is based on the solutions from the subproblems. x = {20.445523142, -2.445523142}
