Suppose that a, b, c are distinct numbers such that (b - a)^2 = 4(b - c)(c - a) = 0. Find the value of (b - c)/(c - a).
+36916 If 4 (b-c)(c-a) = 0 then either b-c = 0 or c-a = 0
then (b-c)/(c-a) either equals 0 (when b-c = 0) or is 'undefined'
+36916 If 4 (b-c)(c-a) = 0 then either b-c = 0 or c-a = 0
then (b-c)/(c-a) either equals 0 (when b-c = 0) or is 'undefined'
