Find the number of terms in the expansion of [(x+y)^3(x-y)^3]^2 - Maths - Binomial Theorem

Question

Find the number of terms in the expansion of
[(x+y)^3(x-y)^3]^2

Aakash Sharma · Accepted Answer

[(x + y)3(x -
y)3]2 = [((x +
y)(x - y))3]2 =
[(x2 -
y2)3]2 =
(x2 - y2)3 Ã—
2 = (x2 -
y2)6
Hence, Required number of terms are 6 + 1 =7
