Simplifying x2 + 9 = 20 + -9x Reorder the terms: 9 + x2 = 20 + -9x Solving 9 + x2 = 20 + -9x Solving for variable 'x'. Reorder the terms: 9 + -20 + 9x + x2 = 20 + -9x + -20 + 9x Combine like terms: 9 + -20 = -11 -11 + 9x + x2 = 20 + -9x + -20 + 9x Reorder the terms: -11 + 9x + x2 = 20 + -20 + -9x + 9x Combine like terms: 20 + -20 = 0 -11 + 9x + x2 = 0 + -9x + 9x -11 + 9x + x2 = -9x + 9x Combine like terms: -9x + 9x = 0 -11 + 9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '11' to each side of the equation. -11 + 9x + 11 + x2 = 0 + 11 Reorder the terms: -11 + 11 + 9x + x2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + 9x + x2 = 0 + 11 9x + x2 = 0 + 11 Combine like terms: 0 + 11 = 11 9x + x2 = 11 The x term is 9x. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9x + 20.25 + x2 = 11 + 20.25 Reorder the terms: 20.25 + 9x + x2 = 11 + 20.25 Combine like terms: 11 + 20.25 = 31.25 20.25 + 9x + x2 = 31.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 31.25 Calculate the square root of the right side: 5.590169944 Break this problem into two subproblems by setting (x + 4.5) equal to 5.590169944 and -5.590169944.Subproblem 1
x + 4.5 = 5.590169944 Simplifying x + 4.5 = 5.590169944 Reorder the terms: 4.5 + x = 5.590169944 Solving 4.5 + x = 5.590169944 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = 5.590169944 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 5.590169944 + -4.5 x = 5.590169944 + -4.5 Combine like terms: 5.590169944 + -4.5 = 1.090169944 x = 1.090169944 Simplifying x = 1.090169944Subproblem 2
x + 4.5 = -5.590169944 Simplifying x + 4.5 = -5.590169944 Reorder the terms: 4.5 + x = -5.590169944 Solving 4.5 + x = -5.590169944 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = -5.590169944 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -5.590169944 + -4.5 x = -5.590169944 + -4.5 Combine like terms: -5.590169944 + -4.5 = -10.090169944 x = -10.090169944 Simplifying x = -10.090169944Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.090169944, -10.090169944}
