Is this your equation? \[3x^2 +2xy - 8y^2 - 8x +14y-3\]

yes

Not "why". I meant "y"

umm ok...

Am I not making any sense? damn

It will! Promise.

umm, what method of factorising is this?

REVERSE FOIL
Starting with 3x^2 and 8y^2, what can they be factored into?

3 and 1, x and x
2 and 4, y and y

sorry, but i dont understand what your talking about :/

\[3x \times x = 3x^2\]\[2y \times 4y = 8y^2\] Is that not correct?

yes thats correct

But its a negative so \[-4y \times 2y = -8y^2\]

ok

...."you can factor out"....

mhm i tried that. Btw i never done reverse foil before so is there any other way?

is it possible if you find the greatest common factor?

|dw:1376184367770:dw|

you forgot to completely factor out \[( 8x^2 - 14y)\]

|dw:1376184611607:dw|

mhm yea

Its okay :)

Lets try this again!
Take out your GCF from your polynomial....
\[3x^2 +2xy - 8y^2 - 8x +14y - 3\]

not sure how...

X, Y and your constant are separate cases. Like what I wrote if you scroll up.

still dont get how you got ur GCF...

Do you know what the term GCF is? GREATEST COMMON FACTOR

yea... but how did you get it...

I thought I just showed you and explained it to you..
