Answer:
Fourth - Degree trinomial
Step-by-step explanation:
[tex]6x^4 - 10x + 9[/tex]
It is a polynomial because there is no negative exponent or fractional exponent
We have highest exponent 4. so it is not cubic. For cubic polynomial highest exponent should be 3
Given expression have highest exponent 4 so its fourth degree. We have three terms 6x^4 , -10x and 9. so we say its trinomial.
Hence we name it as Fourth - Degree trinomial
We have 3 terms so this is not a monomial
