Find the equation of the circle passing through (0, 0) and making intercepts a and b on the coordinate axes.

Explanation

To find the equation of the circle that passes through the origin (0, 0) and makes intercepts a and b on the coordinate axes, we can follow these steps:

### Step 1: General Equation of a Circle
The general equation of a circle is given by:
\[ (x - h)^2 + (y - k)^2 = r^2 \]
where \((h, k)\) is the center of the circle and \(r\) is the radius.
