`lim_(x-gtoo)(x^2+b x+b)/(x^2+b x+c)=?`

lim_(x->1)(a x^2+b x+c)/(c x^2+b x+a),a+b+c!=0

Evaluate : lim_(x->oo)(a x^2+b x+c)/(dx^2+e x+f)dot

Evaluate : lim_(xrarroo)(a x^2+b x+c)/(dx^2+e x+f)dot

The value of lim_(x->oo)(a x^2+b x+c)/(dx+e)(a , b , c , d , e in R-{0}) depends on the sign of :

If lim_(x -> oo) (1 + a/x + b/x^2)^(2x)= e^2 then the values of a and b, are

If lim_(x to 1) (ax^(2)+bx+c)/((x-1)^(2))=2 , then (a, b, c) is

If f(x)=lim_(n->oo)((x^2+a x+1)+x^(2n)(2x^2+x+b))/(1+x^(2n))and lim_(x->+-1)f(x) exist, then The value of b is (a)-1 (b). 1 ( c.) 0 (d).2

If f(x)=lim_(n->oo)((x^2+a x+1)+x^(2n)(2x^2+x+b))/(1+x^(2n))and lim_(x->+-1)f(x) exist, then The value of b is (a) -1 (b). 1 ( c.) 0 (d). 2
