You can put this solution on YOUR website!
Add: (5x^2+7y-6z^2),(4y+3x^2), (2y-2x^2)
\n" ); document.write( "Add \"like\" terms:
\n" ); document.write( "5x^2+3x^2-2x^2=6x^2
\n" ); document.write( "7y+4y+2y=13y
\n" ); document.write( "-6z^2
\n" ); document.write( "----------
\n" ); document.write( "6x^2+13y-6z^2
\n" ); document.write( "=============
