Determine whether the expression is a polynomial. If the expression is a polynomial, state whether it is a monomial,
binomial, or trinomial. If the expression is not a polynomial, indicate why not.
-$6 y ^ { 5 } + 8 y ^ { 4 } - 6$
A)binomial
B)monomial
C)trinomial
D)not polynomial, no variable in last term

Question

Quizplus · Accepted Answer

The expression $6y^5 + 8y^4 - 6$ is a polynomial because it consists of terms that are only added or subtracted, each term is a product of a constant and a whole number power of a variable (including $y^0 = 1$ for the last term), and there are no variables in the denominator or under a radical. It is a trinomial because it has three terms.

Determine Whether the Expression Is a Polynomial 6y5+8y4−66 y ^ { 5 } + 8 y ^ { 4 } - 66y5+8y4−6
