I am sure you meant: (x + 2)^11
there will be 12 terms in the expansion.
they are:
x^11 + V(11,1) (x^10)(2) + C(11,2) (x^9)(2^2) + ... + C(11,9) x^2 (2^9) + C(11,10) x^1 (2^10) + 2^11
which term contains x^2 ??
calculate it.
Consider the expansion of (x + 2)11.
(a) Write down the number of terms in this expansion.
(b) Find the term containing x2.
