Subproblem 1

Set the factor '(50 + -33x + 2x2)' equal to zero and attempt to solve: Simplifying 50 + -33x + 2x2 = 0 Solving 50 + -33x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 25 + -16.5x + x2 = 0 Move the constant term to the right: Add '-25' to each side of the equation. 25 + -16.5x + -25 + x2 = 0 + -25 Reorder the terms: 25 + -25 + -16.5x + x2 = 0 + -25 Combine like terms: 25 + -25 = 0 0 + -16.5x + x2 = 0 + -25 -16.5x + x2 = 0 + -25 Combine like terms: 0 + -25 = -25 -16.5x + x2 = -25 The x term is -16.5x. Take half its coefficient (-8.25). Square it (68.0625) and add it to both sides. Add '68.0625' to each side of the equation. -16.5x + 68.0625 + x2 = -25 + 68.0625 Reorder the terms: 68.0625 + -16.5x + x2 = -25 + 68.0625 Combine like terms: -25 + 68.0625 = 43.0625 68.0625 + -16.5x + x2 = 43.0625 Factor a perfect square on the left side: (x + -8.25)(x + -8.25) = 43.0625 Calculate the square root of the right side: 6.562202374 Break this problem into two subproblems by setting (x + -8.25) equal to 6.562202374 and -6.562202374.
