You can put this solution on YOUR website!
you can only add \"like\" nomials, like, xy^2 + xy^2 or a^2 + a^2 \r
\n" ); document.write( "\n" ); document.write( "not ab^2 + ab^3 or xy + ab^2 \r
\n" ); document.write( "\n" ); document.write( "soooo...\r
\n" ); document.write( "\n" ); document.write( "(5x^2-xy+y^2) + (-x^2-9xy+8y^2) for the answer, i will put them in decending order\r
\n" ); document.write( "\n" ); document.write( "9y^2+4x^2-10xy
\n" ); document.write( "
\n" );
