Chapter 8.4, Problem 6MCQ

To determine

To determine whether the expression is a monomial, binomial or trinomial.

Answer to Problem 6MCQ

Not polynomial.

Explanation of Solution

Given:

Expression: $2x^{-3}-4x+1$

Concept used:

The polynomial can be classified with the number of terms in the expression:

Monomial − A polynomial with only one term

Binomial − A Polynomial with two terms

Trinomial − A polynomial with three terms

Calculation:

Using the concept, the given expression is not a polynomial.

  $\Rightarrow 2x^{-3}-4x+1$

Since, the degree of y is negative.

Conclusion:

Therefore, the given expression is not a polynomial.
