Hi there,
\n" ); document.write( "2n^2 - 21n = 176
\n" ); document.write( "2n^2 - 21n - 176 = 0
\n" ); document.write( "(2n + 11)(n - 16) = 0
\n" ); document.write( "2n + 11 = 0
\n" ); document.write( "n = -5.5 (Disregard as -ve)
\n" ); document.write( "n - 16 = 0
\n" ); document.write( "n = 16
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
\n" );
