Question

What does 13m2n3p + 21mp2 equal when completely factored?
(A)13mp(mn3 + 2p)
(B)m2p2(13n3 + 21)
(C)mp(13mn3 + 21p)
(D)mnp(13mn2 + 21p)

Answer 1

i know this one!

Answer 2

It looks like you can factor out an m and p.

Answer 3

let me do it!

Answer 4

dude!

Answer 5

Also. combine all numbers since they are just constants. So multiply 13 x 2 x 3 :)

Answer 6

um nvm i dont no this

Answer 7

Put constants and variables together but keep them separate so you can see

Answer 8

idk i think so

Answer 9

let meh try

Answer 10

wait, nevermind, are those 3 and 2's mean they are raised to that power?

Answer 11

sry bad at this i am young ok

Answer 12

abb0t yes the 2 and 3 are raised to the power

Answer 13

\(13m^2n^3p +21m p^2\) is that correct?

Answer 14

Ok, simply factor the lowest common factor between them :)

Answer 15

Yes that is correct

Answer 16

Your two common variables are "m" and "p"
That's because you have both of them there. There's no "n" variable on the right side.
Now, notice that you have ONE "p" on the left and ONE "m" on the left.

Those are your common factors.

Answer 17

There's also no two common factors between 13 and 21, so you can just leave them in there.

In essence, you're taking out ONE "m" and ONE "p" only.

Answer 18

Now, can you make what your answer is?

Answer 19

would it be C?

Answer 20

correct

Answer 21

Yep.

Answer 22

thank you
