## Answer

## Step-by-step explanation

Problem to solve:

We can factor the polynomial $x^3+2x^2+x$ using synthetic division (Ruffini's rule). We found that $-1$ is a root of the polynomial

Let's divide the polynomial by $x+1$ using synthetic division. First, write the coefficients of the terms of the numerator in descending order. Then, take the first coefficient $1$ and multiply by the factor $-1$. Add the result to the second coefficient and then multiply this by $-1$ and so on
