If the points ((a^3)/(a-1),(a^2-3)/(a-1)...

If the points `((a^3)/(a-1),(a^2-3)/(a-1)),((b^3)/(b-1),(b^3-3)/(b-1))a n d((c^3)/(c-1),(c^3-3)/(c-1))` where `a , b ,c` are different from 1 lie on the line `l x+m y+n=0` `a+b+c=-m/l` `a b+b c+c a+n/l=0` `a b c=((3m+n))/l` `a b c-(b c+c a+a b)+3(a+b+c)=0`

A

`a +b +c =-(m)/(l)`

B

`abc = (m +pi)/(l ) `

C

`ab + bc + ca =(pi)/(l)`

D

`abc- (ab+bc+ca) + 3 (a+b+c) =0`
