Work Step by Step
To solve by long division, follow these steps. 1) Divide n^2 by to get n. 2) Multiply n(n-4) = n^2 -4n Then subtract. 3) Bring down the remaining 4. 4) Divide -n by n to get -1. 5) Multiply -1(n-4) to get -n+4 and then subtract. leaving you with a remainder of 0. Therefore, your answer is n-1.
