Quandaries
and Queries 

Circe Vera Calculus AP (High School) I'm a student, and this is my homework. Lim 3x^{ 3}+ax+a+3 /(x^{ 2}+x2), X>2 

Hi Circe, The first fact that I noticed is that when x = 2, the denominator is zero. That is = 4 2 2 = 0 What value of a makes the numerator equal to zero? When a has this value the numerator has a root of x = 2 and hence (x + 2) is a factor of the numerator. Does this help?Penny
