Subproblem 1

Set the factor '(-234 + 15y + -1y2)' equal to zero and attempt to solve: Simplifying -234 + 15y + -1y2 = 0 Solving -234 + 15y + -1y2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 234 + -15y + y2 = 0 Move the constant term to the right: Add '-234' to each side of the equation. 234 + -15y + -234 + y2 = 0 + -234 Reorder the terms: 234 + -234 + -15y + y2 = 0 + -234 Combine like terms: 234 + -234 = 0 0 + -15y + y2 = 0 + -234 -15y + y2 = 0 + -234 Combine like terms: 0 + -234 = -234 -15y + y2 = -234 The y term is -15y. Take half its coefficient (-7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. -15y + 56.25 + y2 = -234 + 56.25 Reorder the terms: 56.25 + -15y + y2 = -234 + 56.25 Combine like terms: -234 + 56.25 = -177.75 56.25 + -15y + y2 = -177.75 Factor a perfect square on the left side: (y + -7.5)(y + -7.5) = -177.75 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
