To use the quadratic formula, get it into the form,
\n" ); document.write( " $\"ax%5E2%2Bbx%2Bc=0\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"4x%5E2=2x-11\"$
\n" ); document.write( " $\"4x%5E2-2x%2B11=0\"$
\n" ); document.write( "Now for the quadratic formula,
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%28-%28-2%29+%2B-+sqrt%28+%28-2%29%5E2-4%2A4%2A11+%29%29%2F%282%2A4%29+\"$
\n" ); document.write( " $\"x+=+%282+%2B-+sqrt%28+4-176%29%29%2F%288%29+\"$
\n" ); document.write( " $\"x+=+%282+%2B-+sqrt%28+-172%29%29%2F%288%29+\"$
\n" ); document.write( " $\"x+=+%282+%2B-+sqrt%28+172%29i%29%2F%288%29+\"$
\n" ); document.write( "or approximately,
\n" ); document.write( " $\"x+=+%282+%2B-+13.114i%29%2F%288%29+\"$
\n" ); document.write( " $\"x+=+0.25+%2B-+1.639i+\"$ \n" ); document.write( "

\n" );
