Simplifying x2 + 11x = 13 Reorder the terms: 11x + x2 = 13 Solving 11x + x2 = 13 Solving for variable 'x'. Reorder the terms: -13 + 11x + x2 = 13 + -13 Combine like terms: 13 + -13 = 0 -13 + 11x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '13' to each side of the equation. -13 + 11x + 13 + x2 = 0 + 13 Reorder the terms: -13 + 13 + 11x + x2 = 0 + 13 Combine like terms: -13 + 13 = 0 0 + 11x + x2 = 0 + 13 11x + x2 = 0 + 13 Combine like terms: 0 + 13 = 13 11x + x2 = 13 The x term is 11x. Take half its coefficient (5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. 11x + 30.25 + x2 = 13 + 30.25 Reorder the terms: 30.25 + 11x + x2 = 13 + 30.25 Combine like terms: 13 + 30.25 = 43.25 30.25 + 11x + x2 = 43.25 Factor a perfect square on the left side: (x + 5.5)(x + 5.5) = 43.25 Calculate the square root of the right side: 6.576473219 Break this problem into two subproblems by setting (x + 5.5) equal to 6.576473219 and -6.576473219.Subproblem 1
x + 5.5 = 6.576473219 Simplifying x + 5.5 = 6.576473219 Reorder the terms: 5.5 + x = 6.576473219 Solving 5.5 + x = 6.576473219 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5.5' to each side of the equation. 5.5 + -5.5 + x = 6.576473219 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = 6.576473219 + -5.5 x = 6.576473219 + -5.5 Combine like terms: 6.576473219 + -5.5 = 1.076473219 x = 1.076473219 Simplifying x = 1.076473219Subproblem 2
x + 5.5 = -6.576473219 Simplifying x + 5.5 = -6.576473219 Reorder the terms: 5.5 + x = -6.576473219 Solving 5.5 + x = -6.576473219 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5.5' to each side of the equation. 5.5 + -5.5 + x = -6.576473219 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = -6.576473219 + -5.5 x = -6.576473219 + -5.5 Combine like terms: -6.576473219 + -5.5 = -12.076473219 x = -12.076473219 Simplifying x = -12.076473219Solution
