Match the expression with its name. 6x4 – 10x + 9 a) not a polynomial b) cubic binomial c) fourth -degree trinomial d) quadratic monomial

Fourth - Degree trinomial

Step-by-step explanation:

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

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
