`lim_(x->oo)(x + x^2)/(1 - 2x^2)` Find the limit. Use l’Hospital’s Rule where appropriate. If there is a more elementary method, consider using it. If l’Hospital’s Rule doesn’t apply, explain why.
apply infinity properties,
Using an easier method,
Look at the highest degree terms. Since they are to the same power, now look at the leading coefficients, which is `-1/2`
