Question

classify -3x^5-2x^3 by degree and number of terms
classify -7x^5-6x^4+4x^3 by degree and number of terms

Answer 1

Do you know what a "term" is? (this is really important to understanding & answering the problem). :)

Answer 2

no i do not.

Answer 3

can you please explain this to me?

Answer 4

A "term" is basically "a number times x raised to a power". The number can be positive or negative.

so...

-3x^2 is a term
5x^6 is a term
x^9 is a term (the number is just 1, so we don't write it)

Answer 5

ok...

Answer 6

The "degree" is "the number to which x is raised"

so

the degree of
-3x^2 is 2
5x^6 is 6
x^9 is 9

Answer 7

ohhhhhhh okay...

Answer 8

So like, random example:

-2x^5 + 2x^3 -6x

That has three TERMS
and the highest DEGREE is 6

So it's a "third degree TRInomial" (tri just means three).

Answer 9

So are the variables considered TERMS?

Answer 10

And the numbers considered DEGREES?

Answer 11

classify -3x^5-2x^3 by degree and number of terms
Degree means the highest power of all terms given in the expression
here we see that the highest power of variable is 5

so degree = 5
and number of terms = 2

classify -7x^5-6x^4+4x^3 by degree and number of terms
Here degree = 5
and number of terms = 3

Answer 12

So that means it is classified as a quintic binomial?

Answer 13

what is quintic ?? never heard of that

Answer 14

@geniusy_2006 it is a binomial with 2 values in it

Answer 15

quintic means the highest power = 5

Answer 16

depends on terms -
1 term monomial, 2 terms binomial, 3 terms trinomial
if you are meaning quadratic.. (its a polynomial of degree 2)
It seems you are getting confused

Answer 17

quintuplets = 5 babies

Answer 18

yes i am getting a little confused.. math has always been a complicated subject for me.. then I have the ACT that I will be taking in June... I have to learn this stuff!
