Question

Use the binomial theorem to expand the binomial.

Answer 1

\[(d-5)^6\]

I have it expanded, so I just need my answer checked....What I got was:

\[d^6-30d+375d^4-2500d^3+9375d^2-18750d+15625\]

thank you!

Answer 2

did you use pascal's triangle ??
or did you use factorial method ??
i'll check it:-) ^ tell me how did you solve :)

Answer 3

I had to use the binomial theorem lol
\[(d-5)^6=\sum_{k=0}^{6}\left(\begin{matrix}6 \\ k\end{matrix}\right)d^{6-k}\]
