Limite in forma indeterminata $frac{infty}{infty}$

$lim_{x rightarrow -infty}frac{4x^5+2x+3}{2x^2+3x+1}=$$lim_{x rightarrow -infty}frac{x^5cdot (4+frac{2}{x^4}+frac{3}{x^5})}{x^2cdot (2+frac{3}{x}+frac{1}{x^2})}=$$lim_{x rightarrow -infty}x^3cdotfrac{4+frac{2}{x^4}+frac{3}{x^5}}{2+frac{3}{x}+frac{1}{x^2}}=-infty$
