Answer:
see explanation
Step-by-step explanation:
The equation of a circle in general form is
x² + y² + 2gx + 2fy + c = 0
with centre = (- g, - f) and radius = 
Given
2x² + 2y² + 6x - 8y + 12 = 0 ← divide through by 2
x² + y² + 3x - 4y + 6 = 0 ← in general form
Compare like terms
2g = 3 ⇒ g = 
2f = - 4 ⇒ f = - 2 and c = 6, thus
centre = ( -
, 2 ) and
radius = 
=
=
= 
Answer: The final answer is 10. 10 is the distance between the 2 points given.
