For the identity AB+$$\overline A $$ C + BC= AB + $$\overline A $$ C, The dual form is
A
(a+b)($$\overline A + c$$)(b+c)=(a+b)($$\overline A $$+C)
B
($$\overline A + \overline B )(A + \overline C )(\overline B + \overline C ) = \overline {(A} \, + \overline B )(A + \overline C )$$
C
$$(A + B)(\overline A + C)(B + C) = (\overline A + \overline {B)} (A + \overline C )$$
D
$$\overline A \,\overline B + A\,\overline C + \overline B \,\overline C = \,\overline A \overline B + A\,\overline C $$
