in last step we just compare the powers of variables on LHS and RHS side...you can choose any variable on LHS and RHS...and compare their power...you will get value of n = 1
BUt how can you compare the fractions?
No here i m comparing you to fractions...compare corresponding terms On the either side of equation...i mean compare the power of variable ' a ' on LHS on the numerator part with the variable ' a ' on the RHS in the numerator part also...not with denominator part..
