-2dxy + -8dx2y2 = 0

Solving
-2dxy + -8dx2y2 = 0

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Factor out the Greatest Common Factor (GCF), '-2dxy'.
-2dxy(1 + 4xy) = 0

Ignore the factor -2.

Subproblem 1

Set the factor 'dxy' equal to zero and attempt to solve: Simplifying dxy = 0 Solving dxy = 0 Move all terms containing d to the left, all other terms to the right. Simplifying dxy = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(1 + 4xy)' equal to zero and attempt to solve: Simplifying 1 + 4xy = 0 Solving 1 + 4xy = 0 Move all terms containing d to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + 4xy = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 4xy = 0 + -1 4xy = 0 + -1 Combine like terms: 0 + -1 = -1 4xy = -1 Add '-4xy' to each side of the equation. 4xy + -4xy = -1 + -4xy Combine like terms: 4xy + -4xy = 0 0 = -1 + -4xy Simplifying 0 = -1 + -4xy 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.
