You can put this solution on YOUR website!
First take out the common factor of 4:
\n" ); document.write( " $\"100x%5E4-16y%5E4\"$
\n" ); document.write( " $\"4%2825x%5E4+-+4y%5E4%29+\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Next notice the difference of squares, since $\"25x%5E4\"$ and $\"4y%5E4\"$ are perfect squares. It factors like this:
\n" ); document.write( " $\"4%285x%5E2-+_____%29%2A%285x%5E2%2B+_____%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"4%285x%5E2-2y%5E2%29%2A%285x%5E2%2B+2y%5E2%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "R^2 at SCC
\n" ); document.write( " \n" ); document.write( "
