Subproblem 1

Set the factor '(-1 + -4x + 8x2)' equal to zero and attempt to solve: Simplifying -1 + -4x + 8x2 = 0 Solving -1 + -4x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -0.125 + -0.5x + x2 = 0 Move the constant term to the right: Add '0.125' to each side of the equation. -0.125 + -0.5x + 0.125 + x2 = 0 + 0.125 Reorder the terms: -0.125 + 0.125 + -0.5x + x2 = 0 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + -0.5x + x2 = 0 + 0.125 -0.5x + x2 = 0 + 0.125 Combine like terms: 0 + 0.125 = 0.125 -0.5x + x2 = 0.125 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 = 0.125 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 0.125 + 0.0625 Combine like terms: 0.125 + 0.0625 = 0.1875 0.0625 + -0.5x + x2 = 0.1875 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 0.1875 Calculate the square root of the right side: 0.433012702 Break this problem into two subproblems by setting (x + -0.25) equal to 0.433012702 and -0.433012702.
