Simplifying 16x2 + -8x + 82 = 0 Reorder the terms: 82 + -8x + 16x2 = 0 Solving 82 + -8x + 16x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(41 + -4x + 8x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(41 + -4x + 8x2)' equal to zero and attempt to solve: Simplifying 41 + -4x + 8x2 = 0 Solving 41 + -4x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 5.125 + -0.5x + x2 = 0 Move the constant term to the right: Add '-5.125' to each side of the equation. 5.125 + -0.5x + -5.125 + x2 = 0 + -5.125 Reorder the terms: 5.125 + -5.125 + -0.5x + x2 = 0 + -5.125 Combine like terms: 5.125 + -5.125 = 0.000 0.000 + -0.5x + x2 = 0 + -5.125 -0.5x + x2 = 0 + -5.125 Combine like terms: 0 + -5.125 = -5.125 -0.5x + x2 = -5.125 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = -5.125 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = -5.125 + 0.0625 Combine like terms: -5.125 + 0.0625 = -5.0625 0.0625 + -0.5x + x2 = -5.0625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = -5.0625 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
