\n" ); document.write( "\n" ); document.write( "If you compare this to your problem, the

part is the same as your

part, the

part is the same as your

part, and finally, the

part is the same as your

part.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So if you take the center term apart, in my example the two parts would be

and

, and in your problem they would be

and

. So to find

in my example, you would divide

by 2. Let's do the same for your problem,

. The last term in my example is

, so the last term, or

, in your problem has to be
