Solution:
Given polynomial is:
[tex]x^2 - 6x + 9[/tex]
We have to classify the polynomial
From given,
[tex]x^2 - 6x + 9 \text{ has three terms }[/tex]
[tex]Terms = x^2 , -6x , 9[/tex]
A polynomial with three terms is a trinomial
Thus the given polynomial is a trinomial
What is the degree of the polynomial?
The highest degree of the polynomial 's monomials with non-zero coefficients
[tex]x^2 - 6x + 9\\\\Degree\ of\ x^2 = 2\\\\Degree\ of -6x = 1\\\\Degree\ of\ 9 = 0 ( degree\ of\ constants\ is\ 0)[/tex]
Thus the degree of the polynomial is 2
