Mr. M
Hopefully you can expand ?

Now let and as shown and you can easily evaluate .
7. thanks
8. Alternatively expand if that is the form of Binomial Theorem you are supposed to use.

Why one would want to use Binomial is beyond me, but here

Would you believe me if I said I included a deliberate mistake?

Karma for posting a full solution.
13. Surely there's some background information here? Did they ask you to expand something beforehand?

Here's a snippet of Pascal's triangle (rows go from n = 0 at the top and k = 0 from the left of the row. Alternatively, you can use this equation ):

So the expansion of (a + b)^3 is,

for a and b to equate to 96,
a = 96 and b = -4

Insert these values accordingly and..
