```										Dear nishant
let the polinomial is
x50 + A49x49 +A48 x48...........+ A1 x +A0 =0
whose roots are  (C1/C0) ,22(C2/C1) ,32(C3/C2) ......502(C50/C49)
so   sum of roots = -A49
A49 =  -[ (C1/C0) + 22(C2/C1)+  32(C3/C2)  ......+502(C50/C49)]
=     r :1 to 50  ∑-r2(Cr/C r-1)
=     r  :1 to 50  ∑r2-51r
=   r  :1 to 50  ∑r2     -   r  :1 to 50   ∑51r
=  22100
