Answer: (b-c)x²+(c-a)x+(a-b) = 0
D= b²-4ac = 0
(c-a)²- 4*(b-c)*(a-b) = 0
c²+a²-2ac- 4*(ab-b²-ac+bc) = 0
c²+a²-2ac- 4ab+4b²+4ac-4bc = 0
c²+a²+2ac- 4ab+4b²-4bc = 0
a²+4b²+c²+2ac- 4ab-4bc = 0
a²+(-2b)²+c²+ 2*a*(-2b)+2(-2b)*c+2ac = 0
(a+(-2b)+c)² = 0
Squaring both side,
a+(-2b)+c = 0
a+c = 2b or 2b = a+b
Hope it helps!
