calculus - How to calculate the limit limxto+inftyfracsqrtx2+4x?

So I have another question on limits. In this case the limit is:




lim



I tried to transform it into
\lim_{x\to + \infty} \frac{x^2+4}{x^2}
because I wanted to solve it by factoring but I checked the graph of both and they are different..



I'm stuck here cause my idea doesn't work and I don't know how to solve it!

Could someone be so kind to help me? Thank you in advance! :)
