Arrange the following polynomial into descending order.... (2 Equations!)

Question

anonymous · Answer

These are what they look like :
Arrange the following polynomial into descending order for x, then interpret the degree of the 3rd term.
$$2xy^4 + 2x^2y - 3y^2 + 10x^3$$
Options : 1 , 2 , 3 , 5



Arrange the following polynomial into descending order and identify the 3rd term.
$$-19x^2 + 2 + 4x^3 - 7x$$
Options : -19x^2 , 2 , 4x^3 or -7x

Of course, arrange it first into descending order. Can you do it?

anonymous · Answer

Alright, let's do the first one first. XD

I think this is the order : $$ 10x^3 , 2xy^4 ,  3y^2  , 2x^2y$$

yttrium · Answer

You should be doing the arrangement according to the degree of x. :)

anonymous · Answer

Oh..
So the 2nd equation I put in the order would be first..?

yttrium · Answer

Yes. Therefore, what is the degree of the third term?

anonymous · Answer

Third term = Third Equation, right?
If so, it would be 2.

yttrium · Answer

Yes!

anonymous · Answer

That simple? o_o
I feel like you're only making it this simple. XD

anonymous · Answer

So for the second one, it would be -7x?
@Yttrium

yttrium · Answer

Yes. Don't you worry. It's only the basics of algeb. Factoring and algebraic operations are harder than this, really. :)

anonymous · Answer

Ah okay, can't wait *sarcasm*

But was the Yes to the -7x being the answer?

yttrium · Answer

Yeah. :)

anonymous · Answer

Alright, thanks again! I love your help, xD. So much more helpful, trust me.

yttrium · Answer

Ooops. Apologies if I can't answer your next problems. I need to go. hahaha :D

anonymous · Answer

Not sure if my response came in because of lag but @Yttrium 2 wasn't the answer for the first equation! :( http://gyazo.com/308a4a071639e3451cb9747223cf2fa9

anonymous · Answer

@Yttrium It's fine if you're not here, still wanted to let you know I appreciate it! :)

yttrium · Answer

It's actually one. There are y's over there. We must focus on the degree of x only. But if we are to find the degree of a specific term, we must also consider the degree of other variables.

yttrium · Answer

I mean, 5.

anonymous · Answer

@Yttrium Wait what, it's 5? O_______O Oh sheesh, time to study.

anonymous · Answer

Well thanks anyways!

anonymous · Answer

Actually, the third term is -7x (I just took the test)
