Dear ROHIT,


Ans:- f(x)=x/(x-1)


 f(x+1)=(x+1)/x


Hence  f(a)/f(a+1)=a²/(a² - 1)


                         =f(a²) (Ans)

We have Similarly, So if P(x) = a/2 x 2 +bx +c, then and are off opposite sign and hence there must exist a root between the two numbers.

Got it! [z + 12 – 6 i ] can be rewritten as [ z – i + 12 – 5 i] => | z – i | and => |12 – 5 i | = sqrt ( 12^2 + 5^2) = 13......................(2) => | z + 12 – 6 i | => | z + 12 – 6 i |...
