Subproblem 1

Set the factor '(-16 + -17y + 2y2)' equal to zero and attempt to solve: Simplifying -16 + -17y + 2y2 = 0 Solving -16 + -17y + 2y2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -8 + -8.5y + y2 = 0 Move the constant term to the right: Add '8' to each side of the equation. -8 + -8.5y + 8 + y2 = 0 + 8 Reorder the terms: -8 + 8 + -8.5y + y2 = 0 + 8 Combine like terms: -8 + 8 = 0 0 + -8.5y + y2 = 0 + 8 -8.5y + y2 = 0 + 8 Combine like terms: 0 + 8 = 8 -8.5y + y2 = 8 The y term is -8.5y. Take half its coefficient (-4.25). Square it (18.0625) and add it to both sides. Add '18.0625' to each side of the equation. -8.5y + 18.0625 + y2 = 8 + 18.0625 Reorder the terms: 18.0625 + -8.5y + y2 = 8 + 18.0625 Combine like terms: 8 + 18.0625 = 26.0625 18.0625 + -8.5y + y2 = 26.0625 Factor a perfect square on the left side: (y + -4.25)(y + -4.25) = 26.0625 Calculate the square root of the right side: 5.105144464 Break this problem into two subproblems by setting (y + -4.25) equal to 5.105144464 and -5.105144464.
