Question

How to classify 8x4 + 7x3 + 5x2 + 8 by number of terms.

Answer 1

we are given

`8x^4+7x^3+5x^2+8`

we know that this is polynomial

When number of terms >3 ....then we call that as "polynomial"

We can see that

number of terms =4

so, this is "polynomial of 4 terms"........Answer

Answer 2

This is a polynomial.

Explanation:

A monomial is a constant, a variable or the product of constants and variables.

A binomial is the sum or difference of two monomials.

A trinomial is the sum or difference of three monomials.

Anything more than three terms makes it a polynomial.

This has 4 terms; thus it is a polynomial.
