Simplifying
ex2 + 14xy + -8y4 = 0

Solving
ex2 + 14xy + -8y4 = 0

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

Add '-1ex2' to each side of the equation.
ex2 + 14xy + -1ex2 + -8y4 = 0 + -1ex2

Reorder the terms:
ex2 + -1ex2 + 14xy + -8y4 = 0 + -1ex2

Combine like terms: ex2 + -1ex2 = 0
0 + 14xy + -8y4 = 0 + -1ex2
14xy + -8y4 = 0 + -1ex2
Remove the zero:
14xy + -8y4 = -1ex2

Add '-14xy' to each side of the equation.
14xy + -14xy + -8y4 = -1ex2 + -14xy

Combine like terms: 14xy + -14xy = 0
0 + -8y4 = -1ex2 + -14xy
-8y4 = -1ex2 + -14xy

Add '8y4' to each side of the equation.
-8y4 + 8y4 = -1ex2 + -14xy + 8y4

Combine like terms: -8y4 + 8y4 = 0
0 = -1ex2 + -14xy + 8y4

Simplifying
0 = -1ex2 + -14xy + 8y4
