How to solve Lim [n: ∞, (x ^ (2) + 2x sin (x)) / (2x ^ (2) + cos (x))]?

How to solve Lim [n: ∞, (x ^ (2) + 2x sin (x)) / (2x ^ (2) + cos (x))]?

If the numerator and denominator are divided by x ^ (2), the product of infinitesimal and bounded function is still infinitesimal
That is sin (x) / x ^ (2) = 0 cos (x) / x ^ (2) = 0 (x tends to infinity)
By the way, there is no N in the equation
