Question

Is 2/x-² a polynomial and why

$\sqrt{2} x {}^{2}$
is it a polynomial?


​

Answer 1

ANSWER: Yes both the given equations are polynomials

STEP BY STEP EXPLANATION:

$\frac{2}{ {x}^{ - 2} }$

can be written as

$2 {x}^{2}$

hence it is a polynomial which has a single variable "

$x$

"

also,

$\sqrt{2} x$

is a polynomial since it also has a single variable

here,

$\sqrt{2}$

is acting as the coefficient of x²

Answer 2

Answer:

is a polynomials .If the variable in a polynomial is × ,we may denote the polynomial by p(×) or q(×) ,or (×) ,etc .
