Answer:
Monomial
Trinomial
Monomial
Trinomial
Binomial
Step-by-step explanation:
Monomial = 1 unique term
Binomial = 2 unique terms
Trinomial = 3 unique terms
In the first one, the -x^2 and the +x^2 cancel out, and since 2x and 4x are like terms, you can combine them, leaving you with 6x, a Monomial.
In the second one, after combining +3-2 you have 3 separate terms that cannot be combined, making it a Trinomial
In the third one, all of the variables cancel each other out, leaving you with one term, 3, making it a Monomial
In the fourth one, after combining like temrs, you are left with:
x^3 + 3x^2 + 7x
Making it a Trinomial
In the last one, the 6x and -6x cancel out, leaving you with two terms, making it a Binomial.
