Subproblem 1

Set the factor '(-7 + -2x + 4x2)' equal to zero and attempt to solve: Simplifying -7 + -2x + 4x2 = 0 Solving -7 + -2x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -1.75 + -0.5x + x2 = 0 Move the constant term to the right: Add '1.75' to each side of the equation. -1.75 + -0.5x + 1.75 + x2 = 0 + 1.75 Reorder the terms: -1.75 + 1.75 + -0.5x + x2 = 0 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + -0.5x + x2 = 0 + 1.75 -0.5x + x2 = 0 + 1.75 Combine like terms: 0 + 1.75 = 1.75 -0.5x + x2 = 1.75 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 = 1.75 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 1.75 + 0.0625 Combine like terms: 1.75 + 0.0625 = 1.8125 0.0625 + -0.5x + x2 = 1.8125 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 1.8125 Calculate the square root of the right side: 1.346291202 Break this problem into two subproblems by setting (x + -0.25) equal to 1.346291202 and -1.346291202.

Subproblem 1
