given $\"x%5E2%2B18x%2B4=0\"$ by quadratic formula:
\n" ); document.write( " $\"a=1\"$ , $\"b=18\"$ , & $\"c=4\"$
\n" ); document.write( " $\"x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a\"$
\n" ); document.write( " $\"x=%28-18%2B-sqrt%2818%5E2-4%2A1%2A4%29%29%2F2%2A1\"$
\n" ); document.write( " $\"x=%28-18%2B-sqrt%28324-16%29%29%2F2\"$
\n" ); document.write( " $\"x=%28-18%2B-17.55%29%2F2\"$
\n" ); document.write( " $\"x=-0.225\"$
\n" ); document.write( " $\"x=-17.775\"$
\n" ); document.write( "Check these 2 values of 'x' with the above eqn and you'll get zero.
