Question 346959
AB*CD=DDD

Since D is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.
DDD=AB*CD

Combine all similar variables in the expression.
D^(3)=AB*CD

Multiply AB by CD to get ABCD.
D^(3)=ABCD

Since ABCD contains the variable to solve for, move it to the left-hand side of the equation by subtracting ABCD from both sides.
D^(3)-ABCD=0

Move all terms not containing D to the right-hand side of the equation.
-ABCD+D^(3)=0
