Answer:
4n²+2n as a factorial is given as:
Step-by-step explanation:
We are given an expression which has to be converted into factorial form.
The expression is as follows:
Now we know that 2n+1 and 2n differs by '1' and the next smaller term is '2n-1'.
Hence, multiplying and dividing by '(2n-1)!'; we get:
we know that x(x-1)(x-2)! = x!, so:
It's not clear whether the problem is to:
(1) divide
by 
, or
(2) divide
by 
.
But with only two possible cases, that's not much work to do.
Synthetic division yields a quotient and remainder of
(see attachment for how the algorithm was carried out).
In the other case,
provided that
. Synthetic division can be used again here, but this is quite easy to deal with by just doing some easy manipulation of the numerator:
(also provided that
)
(1) divide
(2) divide
