((3x/(2x-1))+8) Is this a Polynomial

Please tell me if ((3x/(2x-1))+8) is a Polynomial or not

I guess you can't simplify it and it's not a polynomial as the denominator is not resolved

and if we try to solve it using binomial series then it will assume a negative exponent and won't stay a polynomial as polynomials can't have negative powers of variables

but some guys say it's a polynomial please explain with complete reason if its a polynomial or not

Thanks in anticipation.

Hey maddymath.

Its a polynomial only if you can simplify it into linear combinations of positive whole number powers of x (including a constant).

One way apart from the binomial series is through the Taylor series expansion. If there is no Taylor series expansion that gives a bound on the number of non-zero terms then it means the function is not a polynomial.

It can be written as an infinite polynomial, but not a finite one.
