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:

Because the ratio is 1 to 3. It means that For every one apple there are 3 oranges. So If there are 2 apples, there would n 6 oranges. If there are twelve apples, there would be 36 oranges. To find the number of oranges for the amount of apples, just multiply the number of apples by 3.
