Simplifying x2 + x2 + -8x + 16 = 256 Reorder the terms: 16 + -8x + x2 + x2 = 256 Combine like terms: x2 + x2 = 2x2 16 + -8x + 2x2 = 256 Solving 16 + -8x + 2x2 = 256 Solving for variable 'x'. Reorder the terms: 16 + -256 + -8x + 2x2 = 256 + -256 Combine like terms: 16 + -256 = -240 -240 + -8x + 2x2 = 256 + -256 Combine like terms: 256 + -256 = 0 -240 + -8x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-120 + -4x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-120 + -4x + x2)' equal to zero and attempt to solve: Simplifying -120 + -4x + x2 = 0 Solving -120 + -4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '120' to each side of the equation. -120 + -4x + 120 + x2 = 0 + 120 Reorder the terms: -120 + 120 + -4x + x2 = 0 + 120 Combine like terms: -120 + 120 = 0 0 + -4x + x2 = 0 + 120 -4x + x2 = 0 + 120 Combine like terms: 0 + 120 = 120 -4x + x2 = 120 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = 120 + 4 Reorder the terms: 4 + -4x + x2 = 120 + 4 Combine like terms: 120 + 4 = 124 4 + -4x + x2 = 124 Factor a perfect square on the left side: (x + -2)(x + -2) = 124 Calculate the square root of the right side: 11.135528726 Break this problem into two subproblems by setting (x + -2) equal to 11.135528726 and -11.135528726.Subproblem 1
x + -2 = 11.135528726 Simplifying x + -2 = 11.135528726 Reorder the terms: -2 + x = 11.135528726 Solving -2 + x = 11.135528726 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 11.135528726 + 2 Combine like terms: -2 + 2 = 0 0 + x = 11.135528726 + 2 x = 11.135528726 + 2 Combine like terms: 11.135528726 + 2 = 13.135528726 x = 13.135528726 Simplifying x = 13.135528726Subproblem 2
x + -2 = -11.135528726 Simplifying x + -2 = -11.135528726 Reorder the terms: -2 + x = -11.135528726 Solving -2 + x = -11.135528726 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = -11.135528726 + 2 Combine like terms: -2 + 2 = 0 0 + x = -11.135528726 + 2 x = -11.135528726 + 2 Combine like terms: -11.135528726 + 2 = -9.135528726 x = -9.135528726 Simplifying x = -9.135528726Solution
