Subproblem 1

Set the factor '(-1 + -6x + 4x2)' equal to zero and attempt to solve: Simplifying -1 + -6x + 4x2 = 0 Solving -1 + -6x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -0.25 + -1.5x + x2 = 0 Move the constant term to the right: Add '0.25' to each side of the equation. -0.25 + -1.5x + 0.25 + x2 = 0 + 0.25 Reorder the terms: -0.25 + 0.25 + -1.5x + x2 = 0 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + -1.5x + x2 = 0 + 0.25 -1.5x + x2 = 0 + 0.25 Combine like terms: 0 + 0.25 = 0.25 -1.5x + x2 = 0.25 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 0.25 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 0.25 + 0.5625 Combine like terms: 0.25 + 0.5625 = 0.8125 0.5625 + -1.5x + x2 = 0.8125 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 0.8125 Calculate the square root of the right side: 0.901387819 Break this problem into two subproblems by setting (x + -0.75) equal to 0.901387819 and -0.901387819.
