Simplifying 0 = x2 + -10x + -31 Reorder the terms: 0 = -31 + -10x + x2 Solving 0 = -31 + -10x + x2 Solving for variable 'x'. Combine like terms: 0 + 31 = 31 31 + 10x + -1x2 = -31 + -10x + x2 + 31 + 10x + -1x2 Reorder the terms: 31 + 10x + -1x2 = -31 + 31 + -10x + 10x + x2 + -1x2 Combine like terms: -31 + 31 = 0 31 + 10x + -1x2 = 0 + -10x + 10x + x2 + -1x2 31 + 10x + -1x2 = -10x + 10x + x2 + -1x2 Combine like terms: -10x + 10x = 0 31 + 10x + -1x2 = 0 + x2 + -1x2 31 + 10x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 31 + 10x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -31 + -10x + x2 = 0 Move the constant term to the right: Add '31' to each side of the equation. -31 + -10x + 31 + x2 = 0 + 31 Reorder the terms: -31 + 31 + -10x + x2 = 0 + 31 Combine like terms: -31 + 31 = 0 0 + -10x + x2 = 0 + 31 -10x + x2 = 0 + 31 Combine like terms: 0 + 31 = 31 -10x + x2 = 31 The x term is -10x. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10x + 25 + x2 = 31 + 25 Reorder the terms: 25 + -10x + x2 = 31 + 25 Combine like terms: 31 + 25 = 56 25 + -10x + x2 = 56 Factor a perfect square on the left side: (x + -5)(x + -5) = 56 Calculate the square root of the right side: 7.483314774 Break this problem into two subproblems by setting (x + -5) equal to 7.483314774 and -7.483314774.Subproblem 1
x + -5 = 7.483314774 Simplifying x + -5 = 7.483314774 Reorder the terms: -5 + x = 7.483314774 Solving -5 + x = 7.483314774 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = 7.483314774 + 5 Combine like terms: -5 + 5 = 0 0 + x = 7.483314774 + 5 x = 7.483314774 + 5 Combine like terms: 7.483314774 + 5 = 12.483314774 x = 12.483314774 Simplifying x = 12.483314774Subproblem 2
x + -5 = -7.483314774 Simplifying x + -5 = -7.483314774 Reorder the terms: -5 + x = -7.483314774 Solving -5 + x = -7.483314774 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = -7.483314774 + 5 Combine like terms: -5 + 5 = 0 0 + x = -7.483314774 + 5 x = -7.483314774 + 5 Combine like terms: -7.483314774 + 5 = -2.483314774 x = -2.483314774 Simplifying x = -2.483314774Solution
The solution to the problem is based on the solutions from the subproblems. x = {12.483314774, -2.483314774}
