How do you find the limit of #(-6x^4+x^2+1)/(2x^4-x) # as x approaches infinity? Calculus Limits Determining Limits Algebraically 1 Answer José F. Mar 23, 2016 Divide both polynoms by #x^4#. The answer is -3. Explanation: #lim_(x->oo)(-6x^4+x^2+1)/(2x^4-x)=lim_(x->oo)(-6x^4/x^4+x^2/x^4+1/x^4)/(2x^4/x^4-x/x^4)=lim_(x->oo)(-6+1/x^2+1/x^4)/(2-1/x^3)=(-6+0+0)/(2-0)=-3# Answer link Related questions How do you find the limit #lim_(x->5)(x^2-6x+5)/(x^2-25)# ?
