Please determine the following limits if they exist. If the limit does not exist put DNE.
lim 2+6x3x^2 / (2x+1)^2
x>  infinity
lim 4n3 / 3n^2+2
n> infinity
I did
lim 2+6x3x^2 / (2x+1)^2
x>  infinity
(2+6x3x²)/(4x²+4x+1)
(2/x² + 6/x 3)/(4 + 4/x + 1/x²)
as x>  infinity. My answer is 3/4
lim 4n3 / 3n^2+2
n> infinity
Answer is 0.

Precal 
bobpursley,
both are right.
