Question

what is a degree,monomial,binomial, and trinomial? because its asking me to find whether each expression is a polynomial. and if so to find the degree and determined if it is one of those 3 please give me an example by this problem-->d+3d^c

Answer 1

`mono` means `one`
`bi` means `two`
`tri` means `three`

You count the terms between the addition/subtraction signs.
In your example, if we treat d as the variable,
then it is clearly a `bi`nomial because there is one addition sign separating two terms.

Answer 2

The degree is the largest `exponent` of the entire expression.
In your example, it would be a `c`th degree polynomial.

Answer 3

It might be easier to use a number for an exponent since that's probably what all of your problems will be like :)

Answer 4

4x^3 + 2x - 7

In this example, we have a `tri`nomial, a 3-termed expression.
And the largest power of x is a 3, so it's a 3rd degree polynomial.

So all together we would classify this as a `3rd degree trinomial`.

Answer 5

Wanna practice one? :)
Can you classify this one?

7x^2 - 2x + 3

Answer 6

alright so would the degree be 2 and would it be a trinomial?

Answer 7

i mean a binomial

Answer 8

trinomial, three terms, yes!
2nd degree!

not binomial :)
