Simplifying x2 + (x + -9) = 0 Reorder the terms: x2 + (-9 + x) = 0 Remove parenthesis around (-9 + x) x2 + -9 + x = 0 Reorder the terms: -9 + x + x2 = 0 Solving -9 + x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '9' to each side of the equation. -9 + x + 9 + x2 = 0 + 9 Reorder the terms: -9 + 9 + x + x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + x + x2 = 0 + 9 x + x2 = 0 + 9 Combine like terms: 0 + 9 = 9 x + x2 = 9 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = 9 + 0.25 Reorder the terms: 0.25 + x + x2 = 9 + 0.25 Combine like terms: 9 + 0.25 = 9.25 0.25 + x + x2 = 9.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 9.25 Calculate the square root of the right side: 3.041381265 Break this problem into two subproblems by setting (x + 0.5) equal to 3.041381265 and -3.041381265.Subproblem 1
x + 0.5 = 3.041381265 Simplifying x + 0.5 = 3.041381265 Reorder the terms: 0.5 + x = 3.041381265 Solving 0.5 + x = 3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 3.041381265 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 3.041381265 + -0.5 x = 3.041381265 + -0.5 Combine like terms: 3.041381265 + -0.5 = 2.541381265 x = 2.541381265 Simplifying x = 2.541381265Subproblem 2
x + 0.5 = -3.041381265 Simplifying x + 0.5 = -3.041381265 Reorder the terms: 0.5 + x = -3.041381265 Solving 0.5 + x = -3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -3.041381265 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -3.041381265 + -0.5 x = -3.041381265 + -0.5 Combine like terms: -3.041381265 + -0.5 = -3.541381265 x = -3.541381265 Simplifying x = -3.541381265Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.541381265, -3.541381265}
