Subproblem 1

Set the factor 'd' equal to zero and attempt to solve: Simplifying d = 0 Solving d = 0 Move all terms containing d to the left, all other terms to the right. Simplifying d = 0

Subproblem 2

Set the factor '(-1x + xy + y2)' equal to zero and attempt to solve: Simplifying -1x + xy + y2 = 0 Solving -1x + xy + y2 = 0 Move all terms containing d to the left, all other terms to the right. Add 'x' to each side of the equation. -1x + xy + x + y2 = 0 + x Reorder the terms: -1x + x + xy + y2 = 0 + x Combine like terms: -1x + x = 0 0 + xy + y2 = 0 + x xy + y2 = 0 + x Remove the zero: xy + y2 = x Add '-1xy' to each side of the equation. xy + -1xy + y2 = x + -1xy Combine like terms: xy + -1xy = 0 0 + y2 = x + -1xy y2 = x + -1xy Add '-1y2' to each side of the equation. y2 + -1y2 = x + -1xy + -1y2 Combine like terms: y2 + -1y2 = 0 0 = x + -1xy + -1y2 Simplifying 0 = x + -1xy + -1y2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
