Simplifying x * x + 7x = 11 Multiply x * x x2 + 7x = 11 Reorder the terms: 7x + x2 = 11 Solving 7x + x2 = 11 Solving for variable 'x'. Reorder the terms: -11 + 7x + x2 = 11 + -11 Combine like terms: 11 + -11 = 0 -11 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '11' to each side of the equation. -11 + 7x + 11 + x2 = 0 + 11 Reorder the terms: -11 + 11 + 7x + x2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + 7x + x2 = 0 + 11 7x + x2 = 0 + 11 Combine like terms: 0 + 11 = 11 7x + x2 = 11 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = 11 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 11 + 12.25 Combine like terms: 11 + 12.25 = 23.25 12.25 + 7x + x2 = 23.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 23.25 Calculate the square root of the right side: 4.82182538 Break this problem into two subproblems by setting (x + 3.5) equal to 4.82182538 and -4.82182538.Subproblem 1
x + 3.5 = 4.82182538 Simplifying x + 3.5 = 4.82182538 Reorder the terms: 3.5 + x = 4.82182538 Solving 3.5 + x = 4.82182538 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = 4.82182538 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 4.82182538 + -3.5 x = 4.82182538 + -3.5 Combine like terms: 4.82182538 + -3.5 = 1.32182538 x = 1.32182538 Simplifying x = 1.32182538Subproblem 2
x + 3.5 = -4.82182538 Simplifying x + 3.5 = -4.82182538 Reorder the terms: 3.5 + x = -4.82182538 Solving 3.5 + x = -4.82182538 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = -4.82182538 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -4.82182538 + -3.5 x = -4.82182538 + -3.5 Combine like terms: -4.82182538 + -3.5 = -8.32182538 x = -8.32182538 Simplifying x = -8.32182538Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.32182538, -8.32182538}
