You can put this solution on YOUR website!
It sounds like the equation would be:
\n" ); document.write( " $\"2b%5E2-a%5E2\"$
\n" ); document.write( "If so, just replace the b=-1, a=-2, so you have;
\n" ); document.write( " $\"2%28-1%29%5E2-%28-2%29%5E2\"$
\n" ); document.write( " $\"2%281%29-4\"$
\n" ); document.write( " $\"2-4=-2\"$
\n" ); document.write( "If I did not understand the equation correctly, hopefully you can understand what to do. Just replace the b and a in the equation for the numbers given.
\n" ); document.write( "=) \n" ); document.write( "

\n" );
