Comparing the given equation $\"3x%5E2+-+hx+%2B+9+=+0\"$ with the standard quadratic equation $\"ax%5E2%2Bbx%2Bc=0\"$ we find a = 3, b = -h, c = 9.\r

\n" ); document.write( "\n" ); document.write( "Let A and B be the roots of this equation.
\n" ); document.write( "Then, sum of the roots: A + B = $\"-b%2Fa+=+h%2F3\"$ .
\n" ); document.write( "But, given that sum of the roots = -4.
\n" ); document.write( "So $\"h%2F3+=+-4\"$
\n" ); document.write( "or h = -12 \n" ); document.write( "
