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 '(-1vx + -1vy + -1xy + x2)' equal to zero and attempt to solve: Simplifying -1vx + -1vy + -1xy + x2 = 0 Solving -1vx + -1vy + -1xy + x2 = 0 Move all terms containing d to the left, all other terms to the right. Add 'vx' to each side of the equation. -1vx + -1vy + -1xy + vx + x2 = 0 + vx Reorder the terms: -1vx + vx + -1vy + -1xy + x2 = 0 + vx Combine like terms: -1vx + vx = 0 0 + -1vy + -1xy + x2 = 0 + vx -1vy + -1xy + x2 = 0 + vx Remove the zero: -1vy + -1xy + x2 = vx Add 'vy' to each side of the equation. -1vy + -1xy + vy + x2 = vx + vy Reorder the terms: -1vy + vy + -1xy + x2 = vx + vy Combine like terms: -1vy + vy = 0 0 + -1xy + x2 = vx + vy -1xy + x2 = vx + vy Add 'xy' to each side of the equation. -1xy + xy + x2 = vx + vy + xy Combine like terms: -1xy + xy = 0 0 + x2 = vx + vy + xy x2 = vx + vy + xy Add '-1x2' to each side of the equation. x2 + -1x2 = vx + vy + xy + -1x2 Combine like terms: x2 + -1x2 = 0 0 = vx + vy + xy + -1x2 Simplifying 0 = vx + vy + xy + -1x2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
