from where in second line +2 came
it is the identity (a+b)^2=a2+b2+2ab.....so x in numerator and denominator will cancel out leaving 2
and in 33 que third line from where 3^2 +1 came
sorry 3^2-2
i hve taken 3^n+2 common from both the terms
if u multiply 3^n+2 again to 3^2-2 then original terms will be there
can u please send 33rd que
in 33rd que. option c is correct
