Simplifying x2 + -5x + -45 = 0 Reorder the terms: -45 + -5x + x2 = 0 Solving -45 + -5x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '45' to each side of the equation. -45 + -5x + 45 + x2 = 0 + 45 Reorder the terms: -45 + 45 + -5x + x2 = 0 + 45 Combine like terms: -45 + 45 = 0 0 + -5x + x2 = 0 + 45 -5x + x2 = 0 + 45 Combine like terms: 0 + 45 = 45 -5x + x2 = 45 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = 45 + 6.25 Reorder the terms: 6.25 + -5x + x2 = 45 + 6.25 Combine like terms: 45 + 6.25 = 51.25 6.25 + -5x + x2 = 51.25 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 51.25 Calculate the square root of the right side: 7.158910532 Break this problem into two subproblems by setting (x + -2.5) equal to 7.158910532 and -7.158910532.Subproblem 1
x + -2.5 = 7.158910532 Simplifying x + -2.5 = 7.158910532 Reorder the terms: -2.5 + x = 7.158910532 Solving -2.5 + x = 7.158910532 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 7.158910532 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 7.158910532 + 2.5 x = 7.158910532 + 2.5 Combine like terms: 7.158910532 + 2.5 = 9.658910532 x = 9.658910532 Simplifying x = 9.658910532Subproblem 2
x + -2.5 = -7.158910532 Simplifying x + -2.5 = -7.158910532 Reorder the terms: -2.5 + x = -7.158910532 Solving -2.5 + x = -7.158910532 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -7.158910532 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -7.158910532 + 2.5 x = -7.158910532 + 2.5 Combine like terms: -7.158910532 + 2.5 = -4.658910532 x = -4.658910532 Simplifying x = -4.658910532Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.658910532, -4.658910532}
