Hi
we can write: f(x)= (x-2)^2
So for f(x+2), we replace x in f(x) by x+2
That means: f(x+2)= (x+2-2)^2=x^2.
Then the answer is x^2 and you are right.
Hope that you understand.
I think that it's 13.20? not very sure!
Given:
The two numbers are


To find:
The highest common factor (HCF) of A and B
Solution:
We have,
...(i)

All the factors of A are prime but the factors of B are not prime. So, it can be written as
...(ii)
From (i) and (ii), it is clear that 3 is the only common factor of A and B. So,

Therefore, the highest common factor (HCF) of A and B is 3.
