Answer 2

Answer:

We know that a polynomial is a mathematical expression consisting of a sum of terms, each term including a variable or variables raised to a power (usually positive whole number) and multiplied by a coefficient.

The simplest polynomials have one variable.

A one-variable polynomial of degree n has the following form:

a

n

x

n

+a

n−1

x

n−1

+...+a

2

x

2

+a

1

x

1

+a

where, the a's represent the coefficients and x represents the variable.

Now, in the expression

y

5x

4

+7x

2

y

2

−8

, it is clear that the variable y is in the denominator which means that the exponent of the variable y will become −1 when it will be expressed as a numerator and we know that −1 is a negative number, so the expression is not a polynomial.

Hence,

y

5x

4

+7x

2

y

2

−8

is not a polynomial.
