lim_{x→ ∞}(3x²−x−25x²+4x+1 )

Разделите на наибольшую степень знаменателя: 3−1x −2x² 5+4x +1x²

=lim_{x→ ∞}(3−1x −2x² 5+4x +1x² )

lim_x→a[f(x)g(x) ]=lim_x→af(x)lim_x→ag(x) , lim_x→ag(x)≠0
За исключением неопределенной формы

=lim_{x→ ∞}(3−1x −2x² )lim_{x→ ∞}(5+4x +1x² )

lim_{x→ ∞}(3−1x −2x² )=3

lim_{x→ ∞}(5+4x +1x² )=5
