Simplifying x2 + -5x + -3 = 40 Reorder the terms: -3 + -5x + x2 = 40 Solving -3 + -5x + x2 = 40 Solving for variable 'x'. Reorder the terms: -3 + -40 + -5x + x2 = 40 + -40 Combine like terms: -3 + -40 = -43 -43 + -5x + x2 = 40 + -40 Combine like terms: 40 + -40 = 0 -43 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '43' to each side of the equation. -43 + -5x + 43 + x2 = 0 + 43 Reorder the terms: -43 + 43 + -5x + x2 = 0 + 43 Combine like terms: -43 + 43 = 0 0 + -5x + x2 = 0 + 43 -5x + x2 = 0 + 43 Combine like terms: 0 + 43 = 43 -5x + x2 = 43 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 = 43 + 6.25 Reorder the terms: 6.25 + -5x + x2 = 43 + 6.25 Combine like terms: 43 + 6.25 = 49.25 6.25 + -5x + x2 = 49.25 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 49.25 Calculate the square root of the right side: 7.017834424 Break this problem into two subproblems by setting (x + -2.5) equal to 7.017834424 and -7.017834424.Subproblem 1
x + -2.5 = 7.017834424 Simplifying x + -2.5 = 7.017834424 Reorder the terms: -2.5 + x = 7.017834424 Solving -2.5 + x = 7.017834424 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 = 7.017834424 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 7.017834424 + 2.5 x = 7.017834424 + 2.5 Combine like terms: 7.017834424 + 2.5 = 9.517834424 x = 9.517834424 Simplifying x = 9.517834424Subproblem 2
x + -2.5 = -7.017834424 Simplifying x + -2.5 = -7.017834424 Reorder the terms: -2.5 + x = -7.017834424 Solving -2.5 + x = -7.017834424 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 = -7.017834424 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -7.017834424 + 2.5 x = -7.017834424 + 2.5 Combine like terms: -7.017834424 + 2.5 = -4.517834424 x = -4.517834424 Simplifying x = -4.517834424Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.517834424, -4.517834424}
