Tomamos como el límite
$$\lim_{h \to 0^+}\left(\frac{2 h^{3} + \left(- 5 h^{2} + h\right)}{h^{4} - h^{2}}\right)$$
cambiamos
$$\lim_{h \to 0^+}\left(\frac{2 h^{3} + \left(- 5 h^{2} + h\right)}{h^{4} - h^{2}}\right)$$
=
$$\lim_{h \to 0^+}\left(\frac{h \left(2 h^{2} - 5 h + 1\right)}{h^{2} \left(h - 1\right) \left(h + 1\right)}\right)$$
=
$$\lim_{h \to 0^+}\left(\frac{2 h^{2} - 5 h + 1}{h^{3} - h}\right) = $$
False
= -oo
Entonces la respuesta definitiva es:
$$\lim_{h \to 0^+}\left(\frac{2 h^{3} + \left(- 5 h^{2} + h\right)}{h^{4} - h^{2}}\right) = -\infty$$
