Work Shown:
Note in step 2, I factored each number in the square root to pull out the largest perfect square factor. From there, I used the rule that 
to break up the roots.
Answer:
Option E
Step-by-step explanation:
The standard equation of circle is:- (x-h)² + (y-k)² = r²
where (h,k) is center point and r is radius
If radius r is decreased then also (h,k) remains same, only r² increases
Equation given in question is x² + y² + Cx + Dx + E=0
So, C and D will remain same but E will increase
Step-by-step explanation:
4a=2a+4
C.L.T
4a-2a=4
2a=4
=2
