Subproblem 1

Set the factor '(-1000 + 100x + -1x2)' equal to zero and attempt to solve: Simplifying -1000 + 100x + -1x2 = 0 Solving -1000 + 100x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 1000 + -100x + x2 = 0 Move the constant term to the right: Add '-1000' to each side of the equation. 1000 + -100x + -1000 + x2 = 0 + -1000 Reorder the terms: 1000 + -1000 + -100x + x2 = 0 + -1000 Combine like terms: 1000 + -1000 = 0 0 + -100x + x2 = 0 + -1000 -100x + x2 = 0 + -1000 Combine like terms: 0 + -1000 = -1000 -100x + x2 = -1000 The x term is -100x. Take half its coefficient (-50). Square it (2500) and add it to both sides. Add '2500' to each side of the equation. -100x + 2500 + x2 = -1000 + 2500 Reorder the terms: 2500 + -100x + x2 = -1000 + 2500 Combine like terms: -1000 + 2500 = 1500 2500 + -100x + x2 = 1500 Factor a perfect square on the left side: (x + -50)(x + -50) = 1500 Calculate the square root of the right side: 38.729833462 Break this problem into two subproblems by setting (x + -50) equal to 38.729833462 and -38.729833462.
