### "n^2 and 2n^2 is an increase by a factor of 4": how??

In one of my math problems the answer stated that going from n^2 to 2n^2 is an increase by a factor of 4. I dont understand how this is. Can someone explain?

If the expressions are as posted -- n2 and 2n2 -- then the increase is not a factor of 4, but a factor of 2. If, on the other hand, the second expression is (2n)2, then the expression simplifies to 4n2, which is an increase by a factor of 4.

Thanks alot. I thought about this last night and came to the same conclusion that I was "assuming" that the equation was like this 2(n^2) vs (2n)^2. Thanks!
