x^2y-36y+6x^2-216\r
\n" ); document.write( "\n" ); document.write( "y(x^2-36)+6(x^2-36)
\n" ); document.write( "(x^2-36)(x+6)\r
\n" ); document.write( "\n" ); document.write( "using identities
\n" ); document.write( "a^2-b^2= (a+b)(a-b)\r
\n" ); document.write( "\n" ); document.write( "(x+6)(x-6)(x+6)
\n" ); document.write( "(x+6)^2(x-6)
\n" ); document.write( "
\n" );
