only for my friends​

Answer 1

Answer:

(a- b ) × (b-c) ×( c-a?)

Step-by-step explanation:

If the roots of the equation (a - b)X + (b-c)x+ (c-a)=0 are equal,show thatc,a and b are in AP....

Answer 2

Answer:

well, c,a,b are in A.P if 2a = b + c. Also,if roots of a quadratic polynomial is equal, then its discriminant must be zero.
