The given expression is: 
Now, the BINOMIAL EXPANSION is the expansion which describes the algebraic expansion of powers of a binomial.
Here, 
or, on simplification, the terms of the expansion are:

The above statement holds for each n > 0
Hence, the complete expansion for the given expression is given as above.
5/24 because you have to do 5/6 times 1/4
Answer: 124
Step-by-step explanation:
So for this, our equation is gonna be
Firstly, reverse the signs in (x+2) 
Next, change 3x^-4 to 3/x^4, and your answer will be
