Simplifying x2 + -9x = 8 Reorder the terms: -9x + x2 = 8 Solving -9x + x2 = 8 Solving for variable 'x'. Reorder the terms: -8 + -9x + x2 = 8 + -8 Combine like terms: 8 + -8 = 0 -8 + -9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '8' to each side of the equation. -8 + -9x + 8 + x2 = 0 + 8 Reorder the terms: -8 + 8 + -9x + x2 = 0 + 8 Combine like terms: -8 + 8 = 0 0 + -9x + x2 = 0 + 8 -9x + x2 = 0 + 8 Combine like terms: 0 + 8 = 8 -9x + x2 = 8 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 = 8 + 20.25 Reorder the terms: 20.25 + -9x + x2 = 8 + 20.25 Combine like terms: 8 + 20.25 = 28.25 20.25 + -9x + x2 = 28.25 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 28.25 Calculate the square root of the right side: 5.315072906 Break this problem into two subproblems by setting (x + -4.5) equal to 5.315072906 and -5.315072906.Subproblem 1
x + -4.5 = 5.315072906 Simplifying x + -4.5 = 5.315072906 Reorder the terms: -4.5 + x = 5.315072906 Solving -4.5 + x = 5.315072906 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 = 5.315072906 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = 5.315072906 + 4.5 x = 5.315072906 + 4.5 Combine like terms: 5.315072906 + 4.5 = 9.815072906 x = 9.815072906 Simplifying x = 9.815072906Subproblem 2
x + -4.5 = -5.315072906 Simplifying x + -4.5 = -5.315072906 Reorder the terms: -4.5 + x = -5.315072906 Solving -4.5 + x = -5.315072906 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 = -5.315072906 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = -5.315072906 + 4.5 x = -5.315072906 + 4.5 Combine like terms: -5.315072906 + 4.5 = -0.815072906 x = -0.815072906 Simplifying x = -0.815072906Solution
