To interpret:The given equation

Answer to Problem 107RE
The given equation
Explanation of Solution
Given information:
The equation
Formula used:
For a given circle with center
This is referred to as the Standard form for the equation of a given circle.
Moreover, if the center of the circle is nothing but the origin that is
Completing Square method:
To apply this method on an equation of the form:
Method- Make sure that the coefficient of
Calculation:
Consider the given equation:
It can also be written as:
Now apply Completing Square Method on the two brackets:
Now shift the extra terms to the right hand side
Simplify it to get:
Recall the identities:
Use this to get:
Compare this with the Standard equation of circle which is
Where
We get:
Thus, the equation
