Question

Is
$\frac{x {}^{2} }{2} - \frac{2}{ {x}^{2} }$
a polynomial? State the reasons if it's/ it's not a polynomial...​

Answer 1

Step-by-step explanation:

ON SIMPLIFICATION WE GET:

(x⁴ - 4) ÷ 2x²

SO IT'S A POLYNOMIAL WITH 1 AND ONLY VARIABLE THAT IS x.

Answer 2

Answer:

No, the expression given is not a polynomial since one of the variable 'x' has an exponent (-2), which does not satisfy the condition of the exponent which states that all the variables in an expression must have their exponents as whole numbers only.
