Step-by-step explanation:
(x+y) =x³+y³+3xy(x+y)
second identity for subtract statement
(x-y)³=x³-y³+3xy(x-y)
I thought if you understand this identity because we learn this identity in 9th class
how we use this identity
example is given in the photo
or if don't understand this then you multiply it almost 3 Time
for ex.4³= 4×4×4
