Question

Combine terms
m^3+2m^2n-3m^2+3mn^2

Answer 1

\[ m ^{3}+2m ^{2}n -3m ^{2}+3mn ^{2}\]

Answer 2

ok mother just add like a boss

Answer 3

first combine like terms

Answer 4

so factor out the whole thing

Answer 5

m^3+2m^2n−3m^2+3mn^2
m^2(m+n)-3mn(m+n)

Answer 6

i hate that

Answer 7

ok lets do this way since we got m^2(m+n)-3mn(m+n)
what do you think we can do?

Answer 8

I just factored out the equation so if you multiply, you will get back your equation.

Answer 9

are you listening thou? cause you don't respond me :(

Answer 10

Sorry. I just don't understand how you got 3mn(m+n). Are we eliminating the exponent ^2?

Answer 11

it just like you divide

Answer 12

first you will need to group them
ex. (m^3+2m^2n)−(3m^2+3mn^2 t) do this first

Answer 13

Okay. Got that part.

Answer 14

then since you can take out (divide) by m^2 from (m^3+2m^2n)
its gonna be like this
m^2(m+2) or if you multiply m^3+2m^2 got it?

Answer 15

what is x times x? its x^2 right? but what is you divide X^2 by x? you get x right?

Answer 16

Sorry. I am having a hard time posting my responses. I don't know if you're receiving everything I type

Answer 17

nope

Answer 18

do you understand so far?

Answer 19

ok so im just gonna go quickly cuz my bedtime passed already

Answer 20

Ok. Thank you

Answer 21

so once you get this m^2(m+n)-3mn(m+n) you can combine like terms. for example 2x+x=3x

Answer 22

just like that it became (m^2-3mn)(m+n)

Answer 23

now you are done! :)

Answer 24

Thank you.

Answer 25

you're welcome !
