You can put this solution on YOUR website!
7Z-3Z^2+9Z
\n" ); document.write( "First put the equation in correct order;
\n" ); document.write( "\"-3z%5E2\"+9z+7z
\n" ); document.write( "Now add together the terms that are exactly alike;
\n" ); document.write( "9z+7z=16z
\n" ); document.write( "you can not add \"-3z%5E2\" to them because it is not the same:
\n" ); document.write( "so you end with;
\n" ); document.write( "\"-3z%5E2\"+16z
\n" ); document.write( "Hope you understand
\n" ); document.write( "=)
