You can put this solution on YOUR website!
Try this:
\n" ); document.write( "Factor:
\n" ); document.write( " $\"225x%5E2k-196y%5E2k\"$ First, factor the k.
\n" ); document.write( " $\"k%28225x%5E2-196y%5E2%29\"$ Notice that inside the parentheses you have the difference of two squares. The difference of two squares can be factored thus:
\n" ); document.write( " $\"A%5E2+-+B%5E2+=+%28A-B%29%28A%2BB%29\"$ For your problem, you have:
\n" ); document.write( " $\"%2815x%29%5E2+-+%2814y%29%5E2+=+%2815x+-+14y%29%2815x+%2B+14y%29\"$ The final answer is:
\n" ); document.write( " $\"225x%5E2k+-+196y%5E2k+=+k%2815x+-+14y%29%2815x+%2B+14y%29\"$ \n" ); document.write( "

\n" );
