using the formula:
(a+b)³=a³+b³+3ab²+ 3a²b
we find the value of
(4a+3)³=64a³+27+144a²+108a
now we use another formula:
(a-b)³=a³-b³-3a²b+3ab².
(4a-3)³=64a³-27-144a²+108a
according to question:
we have to find the value of
(4a-b)³+(4a+b)³
=64a³-27-144a²+108a-(64a³+27+144a²+108)
=64a³-27+-144a²+108a-64a³-27-144a²-108
= -54-288a².
