Question

y+1/y State whether the given algebraic expression are polynomials? Justify.

Answer 1

y + 1/y

= y + y^(-1)

No, it is not a polynomial.

Because it has a negative integer (-1) as its power.

Answer 2

*************************************

We know that ,

An algebraic expression in

which the variables involved

have only non-negative

integral powers is called a

polynomial .

**************************************

Here ,

y + 1/y = y + y^-1 is not a

polynomial , because

second term ( y^-1 )

has negative exponent.
