X^2 + y^2 -2y-11=0
x^2 + y^2 -2y=11
x^2 + y^2 -2y + ? = 11 + ?
x^2 + y^2 -2y + 1 = 11 + ?
x^2 + y^2 -2y + 1 = 11 + 1
x^2 + (y-1)^2 = 12

Answer:
B. 
Step-by-step explanation:
The polynomial is 
To write in Standard form, the greatest exponent goes first, down to the least.
The greatest exponent is 3, so
goes first.
is what you end up with
The answer is 5. Work backwards: first add 7 to 9, then divide by 2, then subtract 3.
9+7=16
16/2=8
8-3=5
Cross Check:
5+3=8
8*2=16
16-7=9
Final Answer: 5
