I find it difficult to expand a trinomial using the formula method (factorial method) where you can find the coefficient of any term without expanding the whole trinomial.
I can understand the binomial, but I can't do the trinomial using the general sigma notation method.
Can someone please show me how to do this by using about 2 examples?
Thanks alot
