Subproblem 1

Set the factor '(-5 + -3x + 4x2)' equal to zero and attempt to solve: Simplifying -5 + -3x + 4x2 = 0 Solving -5 + -3x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -1.25 + -0.75x + x2 = 0 Move the constant term to the right: Add '1.25' to each side of the equation. -1.25 + -0.75x + 1.25 + x2 = 0 + 1.25 Reorder the terms: -1.25 + 1.25 + -0.75x + x2 = 0 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + -0.75x + x2 = 0 + 1.25 -0.75x + x2 = 0 + 1.25 Combine like terms: 0 + 1.25 = 1.25 -0.75x + x2 = 1.25 The x term is -0.75x. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75x + 0.140625 + x2 = 1.25 + 0.140625 Reorder the terms: 0.140625 + -0.75x + x2 = 1.25 + 0.140625 Combine like terms: 1.25 + 0.140625 = 1.390625 0.140625 + -0.75x + x2 = 1.390625 Factor a perfect square on the left side: (x + -0.375)(x + -0.375) = 1.390625 Calculate the square root of the right side: 1.179247642 Break this problem into two subproblems by setting (x + -0.375) equal to 1.179247642 and -1.179247642.

Subproblem 1
