\lim _{x \rightarrow \infty} \frac{73 x^3+42 x^2-65}{12 x^3+54 x^2+73}

This expression can be written as:

=\lim _{x \rightarrow \infty} \frac{73 x^3\left(1+\frac{42}{73 x}-\frac{65}{73 x^3}\right)}{12 x^3\left(1+\frac{9}{2 x}+\frac{73}{12 x^3}\right)}

=\lim _{x \rightarrow \infty} \frac{73\left(1+\frac{42}{73 x}-\frac{65}{73 x^3}\right)}{12\left(1+\frac{9}{2 x}+\frac{73}{12 x^3}\right)}

Putting value of limit:

\begin{aligned} & =\frac{73(1)}{12(1)} \\ & =\frac{73}{12} \end{aligned}
