$\"%283x%29%5E2-%286y%29%5E2\"$ since $\"3%5E2=9\"$ and $\"6%5E2=36\"$ we are left with the difference of squares here

\n" ); document.write( " $\"x%5E2-15wy%2B3xy-5wx\"$ lets line up the terms that have like variables
\n" ); document.write( ":
\n" ); document.write( "-15wy -5wy)so factor out a -5 and w -5w(3y+x)
\n" ); document.write( ":
\n" ); document.write( " $\"x%5E2%2B3xy\"$ so factor out an x.........x(x+3y)
\n" ); document.write( ":
\n" ); document.write( "do you see any terms that are alike.... that we can factor out of these terms......yes (3y+x)
\n" ); document.write( ":
\n" ); document.write( "so $\"x%28x%2B3y%29-5w%28x%2B3y%29\"$
