The given polynomial x² + 4x + 7 is not a monomial it is a trinomial because there are three terms which is x², 4x, and 7.
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
We have given a polynomial:
x² + 4x + 7
As we know, the monomial has only one term.
The binomial has two terms.
The trinomial has three terms.
As we can see in the given polynomial there are three terms which is x², 4x, and 7.
Thus, the given polynomial x² + 4x + 7 is not a monomial it is a trinomial because there are three terms which is x², 4x, and 7.
