Simplifying x2 + 3 = -9x Reorder the terms: 3 + x2 = -9x Solving 3 + x2 = -9x Solving for variable 'x'. Reorder the terms: 3 + 9x + x2 = -9x + 9x Combine like terms: -9x + 9x = 0 3 + 9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-3' to each side of the equation. 3 + 9x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + 9x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 9x + x2 = 0 + -3 9x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 9x + x2 = -3 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 = -3 + 20.25 Reorder the terms: 20.25 + 9x + x2 = -3 + 20.25 Combine like terms: -3 + 20.25 = 17.25 20.25 + 9x + x2 = 17.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 17.25 Calculate the square root of the right side: 4.153311931 Break this problem into two subproblems by setting (x + 4.5) equal to 4.153311931 and -4.153311931.Subproblem 1
x + 4.5 = 4.153311931 Simplifying x + 4.5 = 4.153311931 Reorder the terms: 4.5 + x = 4.153311931 Solving 4.5 + x = 4.153311931 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 = 4.153311931 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 4.153311931 + -4.5 x = 4.153311931 + -4.5 Combine like terms: 4.153311931 + -4.5 = -0.346688069 x = -0.346688069 Simplifying x = -0.346688069Subproblem 2
x + 4.5 = -4.153311931 Simplifying x + 4.5 = -4.153311931 Reorder the terms: 4.5 + x = -4.153311931 Solving 4.5 + x = -4.153311931 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 = -4.153311931 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -4.153311931 + -4.5 x = -4.153311931 + -4.5 Combine like terms: -4.153311931 + -4.5 = -8.653311931 x = -8.653311931 Simplifying x = -8.653311931Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.346688069, -8.653311931}
