# How do you find the center and radius of the the circle #x^2 + y^2 + 6/5x - 8/5y - 8 = 0#?

##### 1 Answer

First factorise the original equation, so that you have it in the form of a circle equation:

From this we can see that the radius

#### Explanation:

Starting with the original equation:

which equals:

=

Now factorise the above equation, so that you have it in the form of a circle equation:

The circle equation is:

Where r is the radius. The centre x point and the centre y point are

From this we can see that the radius
