Find the degree of the polynomial. A.2 B.4 C.3 D.1

OpenStudy (lovelyanna):

\[2p^2q-3pq+q^2\]

@jigglypuff314

OpenStudy (luigi0210):

Look for the highest power.

OpenStudy (lovelyanna):

What does that mean? o.O

jigglypuff314 (jigglypuff314):

I'll give examples... like if you have x^2 + x + 1 then 2 is the degree of the polynomial if you have x + x^3 + x^7 + x^2 +5 then it is a 7th degree polynomial because the highest power is the x^7

OpenStudy (lovelyanna):

Then here, the answer is C. 3 ?

jigglypuff314 (jigglypuff314):

.-. I'm not sure... I think the highest number I see is a ^2 ?

OpenStudy (lovelyanna):

Oooh, Oops, my mistake. If now I understand your example correctly, then ya, I guess it's 2 :P

OpenStudy (lovelyanna):

How about this one? How many terms does the polynomial have? \[2p^2q-3pq\] A. 1 B. 3 C. 2 D. 4

OpenStudy (lovelyanna):

Would this also be ^2?

jigglypuff314 (jigglypuff314):

yes :) I think so :P

OpenStudy (lovelyanna):

Ok :) thanks! How about this one? \[6x+x^2-x^4+3\]

OpenStudy (lovelyanna):

A.–x^4 + x^2 + 6x + 3 B.x^4 + x^2 + 6x + 3 C.6x + x^2 + x^4 + 3 D.6x – x^2 – x^4 + 3

jigglypuff314 (jigglypuff314):

order it from greatest power to least

OpenStudy (lovelyanna):

Umm... D?

OpenStudy (lovelyanna):

Oh, wait. Hold on

OpenStudy (lovelyanna):

Ya, D?

jigglypuff314 (jigglypuff314):

other way around

OpenStudy (lovelyanna):

o.O

OpenStudy (lovelyanna):

I don't get it >,<

jigglypuff314 (jigglypuff314):

like if it was x + x^3 + x^7 it should become x^7 + x^3 + x

OpenStudy (lovelyanna):

So... B?

jigglypuff314 (jigglypuff314):

don't forget the negative :)

OpenStudy (lovelyanna):

Why a negative? o.O So it's A?

jigglypuff314 (jigglypuff314):

yeah :P and wasn't there a negative? http://prntscr.com/36zykm

OpenStudy (lovelyanna):

I think that's subtraction? :P

jigglypuff314 (jigglypuff314):

subtraction is adding a negative number :P like x - 1 can be x +(-1)

OpenStudy (lovelyanna):

So then, it's A?
