Question 298944
The easiest way is to graph it by solving for one of the variables

Given: {{{A^2*B^2 = 28}}} Take the square root of both sides
{{{A*B = sqrt(28)}}} Then divide by one of the variables. I am going to solve for A by dividing both sides by B.
{{{highlight(A = sqrt(28)/B)}}}
Now the A with act as the Y cordinate on the graph, and teh B with be the X's.

{{{graph(300,200,-10,10,-10,10, sqrt(28)/x)}}}
