Question

Why is the binomial coefficient formula useful with individual terms in binomial expansions?

A. It does all the multiplying to determine the final value of the binomial.
B. It's a shortcut to a specific coefficient.
C. It finds the coefficient pattern for you without writing out Pascal's triangle.
D. You can find all the coefficients for the entire binomial expansion.

Answer 1

D is certainly true

Answer 2

this is kind of a strange question
but the "binomial coefficient formula" i assume is
\[\dbinom{n}{k}=\frac{n!}{k!(n-k)!}\] will find all the coefficients of the expansion of \((a+b)^n\)
