Question

Is 2x² + 5+√x a polynomial justify your answer?​

Answer 1

Answer:

no

Step-by-step explanation:

No $2x^{2} +5+\sqrt{x}$ is not a polynomial as in a polynomial the variable can only have any non-zero integer as power.

but $\sqrt{x}$ can also be written as $x^{\frac{1}{2} }$ which

and $\frac{1}{2} \neq any \:non \:zero \: integer$
