Find the value of the polynomial x2 - 2x + 1 when x is 2.

Answer 1

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 2

Explanation:

2 + 4
`a^1` -
`a^4`

This is a 4th degree trinomial.

39
`x^3` - 1

This is a 3rd degree binomial.

3
`a^2`

This is a second degree monomial.

`x^2 - 2x +1`

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

`4 - 4 + 1`

`0 + 1`

`1`

Hope that helps!
