Simplifying x2 + -6x + -1(0.222) = 0 Multiply -1 * 0.222 x2 + -6x + -0.222 = 0 Reorder the terms: -0.222 + -6x + x2 = 0 Solving -0.222 + -6x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '0.222' to each side of the equation. -0.222 + -6x + 0.222 + x2 = 0 + 0.222 Reorder the terms: -0.222 + 0.222 + -6x + x2 = 0 + 0.222 Combine like terms: -0.222 + 0.222 = 0.000 0.000 + -6x + x2 = 0 + 0.222 -6x + x2 = 0 + 0.222 Combine like terms: 0 + 0.222 = 0.222 -6x + x2 = 0.222 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = 0.222 + 9 Reorder the terms: 9 + -6x + x2 = 0.222 + 9 Combine like terms: 0.222 + 9 = 9.222 9 + -6x + x2 = 9.222 Factor a perfect square on the left side: (x + -3)(x + -3) = 9.222 Calculate the square root of the right side: 3.036774605 Break this problem into two subproblems by setting (x + -3) equal to 3.036774605 and -3.036774605.Subproblem 1
x + -3 = 3.036774605 Simplifying x + -3 = 3.036774605 Reorder the terms: -3 + x = 3.036774605 Solving -3 + x = 3.036774605 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = 3.036774605 + 3 Combine like terms: -3 + 3 = 0 0 + x = 3.036774605 + 3 x = 3.036774605 + 3 Combine like terms: 3.036774605 + 3 = 6.036774605 x = 6.036774605 Simplifying x = 6.036774605Subproblem 2
x + -3 = -3.036774605 Simplifying x + -3 = -3.036774605 Reorder the terms: -3 + x = -3.036774605 Solving -3 + x = -3.036774605 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = -3.036774605 + 3 Combine like terms: -3 + 3 = 0 0 + x = -3.036774605 + 3 x = -3.036774605 + 3 Combine like terms: -3.036774605 + 3 = -0.036774605 x = -0.036774605 Simplifying x = -0.036774605Solution
