just general definitons:

a TRInomial has 3 terms (tri means three)
a BInomial has 2 terms (bi means two)
a MONOmial has 1 term (mono means one)

the degree is the highest exponent found in the algebraic expression

so they should be pretty easy to solve with that information, but just in case:

1. trinomial, degree of 4
2. binomial, degree of 3
3. monomial, degree of 2

for the final question, all you have to do is plug in 2 for x, so

(2)^2 - 2(2) + 1

4 - 4 + 1

so the answer is 1

Answer:

Step-by-step explanation:

2 + 4[tex]a^1[/tex] - [tex]a^4[/tex]

This is a 4th degree trinomial.

39[tex]x^3[/tex] - 1

This is a 3rd degree binomial.

3[tex]a^2[/tex]

This is a second degree monomial.

[tex]x^2 - 2x +1[/tex]

[tex]2^2-2(2)+1[/tex]

[tex]4 - 4 + 1[/tex]

[tex]0 + 1[/tex]

[tex]1[/tex]

Hope that helps!
