oh this is simple

think a bit about AM GM intequality.. .

answer is a

AM-GM se kaise?

Sum of all roots is

x1+x2... + x4 = 4

product is x1 x2... x4 = 1

not AM = 1

GM = 1

equality holds

hence all roots have to be equal..

the only possible value of a is ?? and of b is??

WOW!!! JUS AMAZING OBSERVATN.........

then LHS is of da form (x-t)^4
T =1

now sab kuch ho jaegA

frm nish bhiyyas eqxns . all roots are = 1 ...........

6*1 = a

4(-1) = b

a+b = 2 ...
