Simplifying x2 = 3 + -9x Solving x2 = 3 + -9x Solving for variable 'x'. Reorder the terms: -3 + 9x + x2 = 3 + -9x + -3 + 9x Reorder the terms: -3 + 9x + x2 = 3 + -3 + -9x + 9x Combine like terms: 3 + -3 = 0 -3 + 9x + x2 = 0 + -9x + 9x -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 = 23.25 20.25 + 9x + x2 = 23.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 23.25 Calculate the square root of the right side: 4.82182538 Break this problem into two subproblems by setting (x + 4.5) equal to 4.82182538 and -4.82182538.Subproblem 1
x + 4.5 = 4.82182538 Simplifying x + 4.5 = 4.82182538 Reorder the terms: 4.5 + x = 4.82182538 Solving 4.5 + x = 4.82182538 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 = 4.82182538 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 4.82182538 + -4.5 x = 4.82182538 + -4.5 Combine like terms: 4.82182538 + -4.5 = 0.32182538 x = 0.32182538 Simplifying x = 0.32182538Subproblem 2
x + 4.5 = -4.82182538 Simplifying x + 4.5 = -4.82182538 Reorder the terms: 4.5 + x = -4.82182538 Solving 4.5 + x = -4.82182538 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 = -4.82182538 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -4.82182538 + -4.5 x = -4.82182538 + -4.5 Combine like terms: -4.82182538 + -4.5 = -9.32182538 x = -9.32182538 Simplifying x = -9.32182538Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.32182538, -9.32182538}
