Is 3x^2+4x^-1+5 a polynomial?​

Answer» ONG>ANSWER:

no \:  \\ because \: equation \: in \: the \: form \: of \\ a _{n}x {}^{n}  + a _{n - 1} {x}^{n - 1}  + ......... + a _{0} \\ where \: n \: is \:equal \: to \: whole \: number \\ is \: called \: polynomial.

so \\ 3 {x}^{2}  + 4x {}^{ - 1}  + 5 \\ is \: not \:  \: polynomial \: because \\ power \: of \: x \: is \: negative  \: ( not \: a \: whole \: number)
