Question

2. Simplify and arrange in descending powers of m: 5m - 4m2 + 3m4 - 2m + 2 + 8m3jj

​

Answer 1

Answer:

In an algebraic expression, if the powers of the variables are whole numbers then the algebraic expression is a polynomial.

(i)

y+

1

y

=y+y-1

Here, one of the powers of y is −1, which is not a whole number. So, y +

1

y

is not a polynomial.
