Could someone check my calculus answers, please?

1. Find lim x -> 3 (9-x^2)/(x^2-4x+3) I got -3/2

2. Find lim x -> -1 (sqrt(5+x)-2)/1+x, I got 1/4 (Only the 5+x is under the square root, just to clarify.)

If these are wrong, could someone please tell me the correct answer and how to get it so I know how?

Thanks so much!
