Simplifying 121 = x2 + 5x Reorder the terms: 121 = 5x + x2 Solving 121 = 5x + x2 Solving for variable 'x'. Reorder the terms: 121 + -5x + -1x2 = 5x + -5x + x2 + -1x2 Combine like terms: 5x + -5x = 0 121 + -5x + -1x2 = 0 + x2 + -1x2 121 + -5x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 121 + -5x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -121 + 5x + x2 = 0 Move the constant term to the right: Add '121' to each side of the equation. -121 + 5x + 121 + x2 = 0 + 121 Reorder the terms: -121 + 121 + 5x + x2 = 0 + 121 Combine like terms: -121 + 121 = 0 0 + 5x + x2 = 0 + 121 5x + x2 = 0 + 121 Combine like terms: 0 + 121 = 121 5x + x2 = 121 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 = 121 + 6.25 Reorder the terms: 6.25 + 5x + x2 = 121 + 6.25 Combine like terms: 121 + 6.25 = 127.25 6.25 + 5x + x2 = 127.25 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 127.25 Calculate the square root of the right side: 11.280514173 Break this problem into two subproblems by setting (x + 2.5) equal to 11.280514173 and -11.280514173.Subproblem 1
x + 2.5 = 11.280514173 Simplifying x + 2.5 = 11.280514173 Reorder the terms: 2.5 + x = 11.280514173 Solving 2.5 + x = 11.280514173 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 = 11.280514173 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 11.280514173 + -2.5 x = 11.280514173 + -2.5 Combine like terms: 11.280514173 + -2.5 = 8.780514173 x = 8.780514173 Simplifying x = 8.780514173Subproblem 2
x + 2.5 = -11.280514173 Simplifying x + 2.5 = -11.280514173 Reorder the terms: 2.5 + x = -11.280514173 Solving 2.5 + x = -11.280514173 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 = -11.280514173 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -11.280514173 + -2.5 x = -11.280514173 + -2.5 Combine like terms: -11.280514173 + -2.5 = -13.780514173 x = -13.780514173 Simplifying x = -13.780514173Solution
The solution to the problem is based on the solutions from the subproblems. x = {8.780514173, -13.780514173}
