Simplifying -1x2 + -5x + 17 = 0 Reorder the terms: 17 + -5x + -1x2 = 0 Solving 17 + -5x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -17 + 5x + x2 = 0 Move the constant term to the right: Add '17' to each side of the equation. -17 + 5x + 17 + x2 = 0 + 17 Reorder the terms: -17 + 17 + 5x + x2 = 0 + 17 Combine like terms: -17 + 17 = 0 0 + 5x + x2 = 0 + 17 5x + x2 = 0 + 17 Combine like terms: 0 + 17 = 17 5x + x2 = 17 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 = 17 + 6.25 Reorder the terms: 6.25 + 5x + x2 = 17 + 6.25 Combine like terms: 17 + 6.25 = 23.25 6.25 + 5x + x2 = 23.25 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 23.25 Calculate the square root of the right side: 4.82182538 Break this problem into two subproblems by setting (x + 2.5) equal to 4.82182538 and -4.82182538.Subproblem 1
x + 2.5 = 4.82182538 Simplifying x + 2.5 = 4.82182538 Reorder the terms: 2.5 + x = 4.82182538 Solving 2.5 + x = 4.82182538 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 = 4.82182538 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 4.82182538 + -2.5 x = 4.82182538 + -2.5 Combine like terms: 4.82182538 + -2.5 = 2.32182538 x = 2.32182538 Simplifying x = 2.32182538Subproblem 2
x + 2.5 = -4.82182538 Simplifying x + 2.5 = -4.82182538 Reorder the terms: 2.5 + x = -4.82182538 Solving 2.5 + x = -4.82182538 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 = -4.82182538 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -4.82182538 + -2.5 x = -4.82182538 + -2.5 Combine like terms: -4.82182538 + -2.5 = -7.32182538 x = -7.32182538 Simplifying x = -7.32182538Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.32182538, -7.32182538}
