Simplifying 0 = -9x2 + 9x + 9 Reorder the terms: 0 = 9 + 9x + -9x2 Solving 0 = 9 + 9x + -9x2 Solving for variable 'x'. Combine like terms: 0 + -9 = -9 -9 + -9x + 9x2 = 9 + 9x + -9x2 + -9 + -9x + 9x2 Reorder the terms: -9 + -9x + 9x2 = 9 + -9 + 9x + -9x + -9x2 + 9x2 Combine like terms: 9 + -9 = 0 -9 + -9x + 9x2 = 0 + 9x + -9x + -9x2 + 9x2 -9 + -9x + 9x2 = 9x + -9x + -9x2 + 9x2 Combine like terms: 9x + -9x = 0 -9 + -9x + 9x2 = 0 + -9x2 + 9x2 -9 + -9x + 9x2 = -9x2 + 9x2 Combine like terms: -9x2 + 9x2 = 0 -9 + -9x + 9x2 = 0 Factor out the Greatest Common Factor (GCF), '9'. 9(-1 + -1x + x2) = 0 Ignore the factor 9.Subproblem 1
Set the factor '(-1 + -1x + x2)' equal to zero and attempt to solve: Simplifying -1 + -1x + x2 = 0 Solving -1 + -1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + -1x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -1x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1x + x2 = 0 + 1 -1x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -1x + x2 = 1 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = 1 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 1 + 0.25 Combine like terms: 1 + 0.25 = 1.25 0.25 + -1x + x2 = 1.25 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 1.25 Calculate the square root of the right side: 1.118033989 Break this problem into two subproblems by setting (x + -0.5) equal to 1.118033989 and -1.118033989.Subproblem 1
x + -0.5 = 1.118033989 Simplifying x + -0.5 = 1.118033989 Reorder the terms: -0.5 + x = 1.118033989 Solving -0.5 + x = 1.118033989 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 1.118033989 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 1.118033989 + 0.5 x = 1.118033989 + 0.5 Combine like terms: 1.118033989 + 0.5 = 1.618033989 x = 1.618033989 Simplifying x = 1.618033989Subproblem 2
x + -0.5 = -1.118033989 Simplifying x + -0.5 = -1.118033989 Reorder the terms: -0.5 + x = -1.118033989 Solving -0.5 + x = -1.118033989 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -1.118033989 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -1.118033989 + 0.5 x = -1.118033989 + 0.5 Combine like terms: -1.118033989 + 0.5 = -0.618033989 x = -0.618033989 Simplifying x = -0.618033989Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.618033989, -0.618033989}Solution
x = {1.618033989, -0.618033989}
