Find the equation for the circle with a diameter whose endpoints are (2,-2) and (-5,4). ????
------------------------------------------------------ 

The center is at (-1.5, 1).

Notice that -1.5 =  and 1 = .

The square of the diameter is  = 85.

Notice that 7 = 2 - (-5),  and  -6 = -2 - 4.

The equation of the circle is 

 = .

The radius of the circle is .
