Factor completely 12x3y + 6x2y2 − 9xy3. 3x2y(4x2 + 2xy − 3) 3xy(4x + 2xy − 3y2) 3xy(4x2 + 2xy − 3y2) 3x2y(4x3y − 2x2y2 − 3xy3)

nolegirl24:

@dude

jhonyy9:

any idea ?

jhonyy9:

what can you factorizing out from : 12 ,6 and 9 ?

jhonyy9:

what is common 3*4 , 3*2 and 3*3 ?

nolegirl24:

Ik the GCF is 3

nolegirl24:

right

jhonyy9:

exactly

jhonyy9:

x^3 , x^2 and x so from these ?

nolegirl24:

It would just be x right?

jhonyy9:

yes nice

jhonyy9:

y ,y^2 and y^3 from these ?

nolegirl24:

Y?

jhonyy9:

yes

jhonyy9:

so you have factorized out 3xy(


) what will remain inside parantheses

nolegirl24:

idk...

jhonyy9:

just you need divide this 12x^3y +6x^2y^2 -9xy^3 by 3xy = ?

jhonyy9:

from 12x^3y than factoriz out 3xy what will get ?

nolegirl24:

4x^2y?

jhonyy9:

factoriz out y from y what will reamain there ?

nolegirl24:

4x^2

jhonyy9:

yes sure

jhonyy9:

second term

nolegirl24:

2xy?

jhonyy9:

very nice 3rd term

nolegirl24:

-3y^2

jhonyy9:

perfect

nolegirl24:

so it would be C?

jhonyy9:

are you sure ?
