Subproblem 1

Set the factor '(-33 + -1x + 2x2)' equal to zero and attempt to solve: Simplifying -33 + -1x + 2x2 = 0 Solving -33 + -1x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -16.5 + -0.5x + x2 = 0 Move the constant term to the right: Add '16.5' to each side of the equation. -16.5 + -0.5x + 16.5 + x2 = 0 + 16.5 Reorder the terms: -16.5 + 16.5 + -0.5x + x2 = 0 + 16.5 Combine like terms: -16.5 + 16.5 = 0.0 0.0 + -0.5x + x2 = 0 + 16.5 -0.5x + x2 = 0 + 16.5 Combine like terms: 0 + 16.5 = 16.5 -0.5x + x2 = 16.5 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 = 16.5 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 16.5 + 0.0625 Combine like terms: 16.5 + 0.0625 = 16.5625 0.0625 + -0.5x + x2 = 16.5625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 16.5625 Calculate the square root of the right side: 4.069705149 Break this problem into two subproblems by setting (x + -0.25) equal to 4.069705149 and -4.069705149.

Subproblem 1
