Simplifying x2 + -23x + -40 = 0 Reorder the terms: -40 + -23x + x2 = 0 Solving -40 + -23x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '40' to each side of the equation. -40 + -23x + 40 + x2 = 0 + 40 Reorder the terms: -40 + 40 + -23x + x2 = 0 + 40 Combine like terms: -40 + 40 = 0 0 + -23x + x2 = 0 + 40 -23x + x2 = 0 + 40 Combine like terms: 0 + 40 = 40 -23x + x2 = 40 The x term is -23x. Take half its coefficient (-11.5). Square it (132.25) and add it to both sides. Add '132.25' to each side of the equation. -23x + 132.25 + x2 = 40 + 132.25 Reorder the terms: 132.25 + -23x + x2 = 40 + 132.25 Combine like terms: 40 + 132.25 = 172.25 132.25 + -23x + x2 = 172.25 Factor a perfect square on the left side: (x + -11.5)(x + -11.5) = 172.25 Calculate the square root of the right side: 13.124404748 Break this problem into two subproblems by setting (x + -11.5) equal to 13.124404748 and -13.124404748.Subproblem 1
x + -11.5 = 13.124404748 Simplifying x + -11.5 = 13.124404748 Reorder the terms: -11.5 + x = 13.124404748 Solving -11.5 + x = 13.124404748 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '11.5' to each side of the equation. -11.5 + 11.5 + x = 13.124404748 + 11.5 Combine like terms: -11.5 + 11.5 = 0.0 0.0 + x = 13.124404748 + 11.5 x = 13.124404748 + 11.5 Combine like terms: 13.124404748 + 11.5 = 24.624404748 x = 24.624404748 Simplifying x = 24.624404748Subproblem 2
x + -11.5 = -13.124404748 Simplifying x + -11.5 = -13.124404748 Reorder the terms: -11.5 + x = -13.124404748 Solving -11.5 + x = -13.124404748 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '11.5' to each side of the equation. -11.5 + 11.5 + x = -13.124404748 + 11.5 Combine like terms: -11.5 + 11.5 = 0.0 0.0 + x = -13.124404748 + 11.5 x = -13.124404748 + 11.5 Combine like terms: -13.124404748 + 11.5 = -1.624404748 x = -1.624404748 Simplifying x = -1.624404748Solution
