Answer:
(x+3)², if looking for x, X = -3
Step-by-step explanation:
X²+6x+9 is a perfect square as you immediately can see that 3+3 = 6 and 3*3 = 9.
I used the generic rectangle to solve it, 9 into top right corner and then x² onto the bottom left, multiplying eachother to get 9x² which is formed by 3x and 3x multiplied so you would have (x+3) (x+3).
I'll have a picture.

Answer:
so a=36, b=3, c=5, d=540
Apparently k=6. It doesn't say it in the question, but I'll assume that you had a mistype and forgot to say that the second term is 12.
Anyway,
The nth term of a geometric sequence is
. Thus, the 52nd term would be 
and the 50th term would be 
When you divide the two, the 2's would cancel out and k^49 would cancel out, leaving you with 1 on the bottom and k^2 on the top. As we said at the beginning, k=6, so our answer is just 6*6=36.
Anyway,
The nth term of a geometric sequence is
