$\"+x%5E2+%2B+11x+%2B+30+=+0+\"$
\n" ); document.write( "( it is set to zero to finds the roots )
\n" ); document.write( "Subtract $\"+30+\"$ from both sides
\n" ); document.write( " $\"+x%5E2+%2B+11x+=+-30+\"$
\n" ); document.write( "---------------------
\n" ); document.write( "To complete the square, take 1/2 of
\n" ); document.write( "the coefficient of the $\"+x+\"$ term,
\n" ); document.write( "square it, and add it to both sides
\n" ); document.write( "------------------------------
