You can put this solution on YOUR website!
Notice that you can \"factor\" it:
\n" ); document.write( "81x^2-144=0
\n" ); document.write( "(9x+12)(9-12)=0
\n" ); document.write( ".
\n" ); document.write( "therefore:
\n" ); document.write( "x = {-12,12}
\n" ); document.write( "
\n" ); document.write( "
\n" );
