Answer
Normally you would fator in order to find the common factor and eliminate it. In that way you can simplify it.
$x$

If the numerator and the denominator of a rational expression have a common factor, how would you simplify the expression?
Normally you would fator in order to find the common factor and eliminate it. In that way you can simplify it.
$$\frac{x^{2}+x}{x+1}$$ $$\frac{x(x+1)}{x+1}$$
Now we know that the common factor is $(x+1)$ so we can eliminate it and end up with
$$x$$
$x$ is the answer.
