Simplifying x2 + 9x + 2 = 0 Reorder the terms: 2 + 9x + x2 = 0 Solving 2 + 9x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + 9x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + 9x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 9x + x2 = 0 + -2 9x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 9x + x2 = -2 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 = -2 + 20.25 Reorder the terms: 20.25 + 9x + x2 = -2 + 20.25 Combine like terms: -2 + 20.25 = 18.25 20.25 + 9x + x2 = 18.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 18.25 Calculate the square root of the right side: 4.272001873 Break this problem into two subproblems by setting (x + 4.5) equal to 4.272001873 and -4.272001873.Subproblem 1
x + 4.5 = 4.272001873 Simplifying x + 4.5 = 4.272001873 Reorder the terms: 4.5 + x = 4.272001873 Solving 4.5 + x = 4.272001873 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 = 4.272001873 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 4.272001873 + -4.5 x = 4.272001873 + -4.5 Combine like terms: 4.272001873 + -4.5 = -0.227998127 x = -0.227998127 Simplifying x = -0.227998127Subproblem 2
x + 4.5 = -4.272001873 Simplifying x + 4.5 = -4.272001873 Reorder the terms: 4.5 + x = -4.272001873 Solving 4.5 + x = -4.272001873 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 = -4.272001873 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -4.272001873 + -4.5 x = -4.272001873 + -4.5 Combine like terms: -4.272001873 + -4.5 = -8.772001873 x = -8.772001873 Simplifying x = -8.772001873Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.227998127, -8.772001873}
