Simplifying x2 + -14x + -31 = 0 Reorder the terms: -31 + -14x + x2 = 0 Solving -31 + -14x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '31' to each side of the equation. -31 + -14x + 31 + x2 = 0 + 31 Reorder the terms: -31 + 31 + -14x + x2 = 0 + 31 Combine like terms: -31 + 31 = 0 0 + -14x + x2 = 0 + 31 -14x + x2 = 0 + 31 Combine like terms: 0 + 31 = 31 -14x + x2 = 31 The x term is -14x. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14x + 49 + x2 = 31 + 49 Reorder the terms: 49 + -14x + x2 = 31 + 49 Combine like terms: 31 + 49 = 80 49 + -14x + x2 = 80 Factor a perfect square on the left side: (x + -7)(x + -7) = 80 Calculate the square root of the right side: 8.94427191 Break this problem into two subproblems by setting (x + -7) equal to 8.94427191 and -8.94427191.Subproblem 1
x + -7 = 8.94427191 Simplifying x + -7 = 8.94427191 Reorder the terms: -7 + x = 8.94427191 Solving -7 + x = 8.94427191 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + x = 8.94427191 + 7 Combine like terms: -7 + 7 = 0 0 + x = 8.94427191 + 7 x = 8.94427191 + 7 Combine like terms: 8.94427191 + 7 = 15.94427191 x = 15.94427191 Simplifying x = 15.94427191Subproblem 2
x + -7 = -8.94427191 Simplifying x + -7 = -8.94427191 Reorder the terms: -7 + x = -8.94427191 Solving -7 + x = -8.94427191 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + x = -8.94427191 + 7 Combine like terms: -7 + 7 = 0 0 + x = -8.94427191 + 7 x = -8.94427191 + 7 Combine like terms: -8.94427191 + 7 = -1.94427191 x = -1.94427191 Simplifying x = -1.94427191Solution
The solution to the problem is based on the solutions from the subproblems. x = {15.94427191, -1.94427191}
