The blue circle has radius 2 and the green circle has radius 1 AB is a common tangent and all 3 circles touch each other. Find the radius of the smallest circle. The answer is btw 6 - 4√2 how ever I'm only getting as to far as (6-2√2)/7 Please solve with working

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
