Calc. Limits

Are these correct?
lim x>0 (x)/(sqrt(x^2+4)  2)
I get 4/0= +/ infinity so lim x>0+ = + infinity? and lim x>0 = + infinity?
lim x>1 (x^2  5x + 6)/(x^2  3x + 2)
I get 2/0, so lim x> 1+ =  infinity? and lim x>1 = + infinity?
lim h>0 [(7)/(2+h^2) + (7/4)]/h
I used a computational website to get (7/4) as the answer, but I did not get this. My work ends with: (28)/(4(h+8) + (7(h+8)/(4(h+8)) and I end with 5.25 for an answer?
Last one!
lim x> neg. infinity (2x^2 + 3x  2)/(5x^3 + 4x x + 1)
Don't even know about this one?
Please help. I would like to understand these.
