Question

simplify, arranging terms in order of decreasing degree of x. then write the degree of the polynomial.

1-5x^3 + 3x^2 - 2 + 5x^2

Answer 1

The degree of the polynomial is the highest power of x.

Answer 2

so its 3?

Answer 3

correct. well done.

Answer 4

and then how would i simplify?

Answer 5

thanks btw

Answer 6

collect like terms

Answer 7

In that polynomial I see two terms alike with x^2

Answer 8

ok, so add -5x^3 with 3x^2

Answer 9

Absolutely.

Answer 10

so its -2x^2?

Answer 11

Now rearrange it from highest to lowest in terms of the power of x.

Answer 12

Yes.

Answer 13

ok. and is the degree of the polynomial found before or after I simplify?

Answer 14

and can an x^2 and x^3 be added together when simplifying?

Answer 15

No, because x^3 is not x^2. You cannot collect like terms with different powers of x.

Answer 16

ok

Answer 17

You have to also simply the -1 and -2

Answer 18

1*

Answer 19

ok, which would be -3. and then how about the degree of the polynomial question?

Answer 20

You have to collect all the like terms when you're simplifying. And yes, that's correct.

Answer 21

No that's not correct sorry.

Answer 22

1-2=?

Answer 23

-1

Answer 24

Now you're correct.

Answer 25

i thought you meant -1 + -2

Answer 26

but do i find the degree of the polynomial before or after simplifying?

Answer 27

A question tells you to simplify first. What do you think you have to do first in this case? Because I thought you knew how to simplify. I just told you the definition of the degree.

Answer 28

of the degree of a polynomial*

Answer 29

ok
thanks for your help, you seem to be getting annoyed. have a nice evening :)

Answer 30

You're welcome.
