lim_(x->∞) (sqrt(4 x^2 + x) + (sqrt(9 x^2 - x) - 5 x)) = 1/12 can you help me to solve this?

lim_(x->∞) (sqrt(4 x^2 + x) + (sqrt(9 x^2 - x) - 5 x)) = 1/12

$$\displaystyle\lim_{x\rightarrow \infty}\;\;[\sqrt{4 x^2 + x}+ \sqrt{9 x^2 - x} - 5 x]= \frac{1}{12}$$

There is nothing to solve.  This is either true or not true and it is not true

Have you written the question incorrectly?
