If r and s are variables satisfying the equation `(1)/(r+s) =1/r+1/s. ` The value of `((r )/(s ))^(3)` is equal to :

If r and s are the roots of the equation ax^2+ bx + c= 0 , then the value of 1/r^2+1/s^2=

3(r+2s)=r+s If (r, s) is a solution to the equation above and sne0 , what is the value of (r)/(s) ?

If (2rs)^(-1)=3s^(-2) , what is the value of (r)/(s) ?

If s(r)=2+2r+2r^(2)+.....oo and "s(a)times s(-a)=420 , where a,r in(-1,1) . Then the value of (s(a)+s(-a))/(15) is equal to
