Step-by-step explanation:
The standard form of the equation of a circle is given as:

Simplifying the above given equation, we get




which is the required general form of the equation.
Hence, option A is correct.
The first and the 2nd one are correct because x is 21 and y is 49
3 and 4 at wrong
X ÷ 4 = 8
Multiply each side by 4
x = 32
He subtracted 4 from 12 and got 8
