The easiest way is to graph it by solving for one of the variables
Given: A%5E2%2AB%5E2+=+28 Take the square root of both sides
A%2AB+=+sqrt%2828%29 Then divide by one of the variables. I am going to solve for A by dividing both sides by B.
highlight%28A+=+sqrt%2828%29%2FB%29
Now the A with act as the Y cordinate on the graph, and teh B with be the X's.
