Subproblem 1

Set the factor '(366 + -11x + -1x2)' equal to zero and attempt to solve: Simplifying 366 + -11x + -1x2 = 0 Solving 366 + -11x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -366 + 11x + x2 = 0 Move the constant term to the right: Add '366' to each side of the equation. -366 + 11x + 366 + x2 = 0 + 366 Reorder the terms: -366 + 366 + 11x + x2 = 0 + 366 Combine like terms: -366 + 366 = 0 0 + 11x + x2 = 0 + 366 11x + x2 = 0 + 366 Combine like terms: 0 + 366 = 366 11x + x2 = 366 The x term is 11x. Take half its coefficient (5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. 11x + 30.25 + x2 = 366 + 30.25 Reorder the terms: 30.25 + 11x + x2 = 366 + 30.25 Combine like terms: 366 + 30.25 = 396.25 30.25 + 11x + x2 = 396.25 Factor a perfect square on the left side: (x + 5.5)(x + 5.5) = 396.25 Calculate the square root of the right side: 19.906029237 Break this problem into two subproblems by setting (x + 5.5) equal to 19.906029237 and -19.906029237.
