Okay now it factors. This is what W|A returns:I'm really sorry. i guess i edited it correctly this time. please bear with me.
I did as I suggested you do in an earlier post. I expanded the factorized form to find a possible method of factoring.how did you know that there are three terms that needs to be split? and why those terms?
did you do trial and error?
our instructor gave us this problem. i don't know from where did he get this.
i want to learn how to solve this. I've used all the method i know to solve this but no success.
please help me.
Hello.paulmdrdo said:would you help me with this
please help me. thanks!
I did not do anything before I had the factored form. It was from the factored form that I saw how rewrite the expression, so that I could demonstrate to you a possible path to take.i wonder how did you arrive at splitting those terms before getting the factored form.
$\displaystyle -\left(3x^3-5x^2y-4xy-9y \right)\left(6x^3y+2x^2-8x+7y^2 \right)$
from this factored form I can get insight of method on how to factor it. but prior to getting this factored form, how did you decide that those three terms should be cut into pieces?
Yes, lots of paper and time for trial and error.OH men! I'm scratching my head for hours wondering how did you easily get that factored form. now I understand. I feel bad about myself that I'm not able get the right factored form.
but at any rate, is there a method to do it manually?
