Is this your equation? \[3x^2 +2xy  8y^2  8x +14y3\]

Sorry, I was trying to get my question answered.. Anyways! What do we know? We know that the following can be factored out: \[x^2\]\[8y^2\]\[14\] I left out 3 and why because they can only be only be factored out by 1.

Not "why". I meant "y"

for some reason i cant factorise this question :/ i dont see taking out these common factors to be any help...

i know its possible to factorise this but i ahve no idea how http://www.wolframalpha.com/input/?i=factorize+3x%5E2+%2B2xy++8y%5E2++8x+%2B14y3

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

ilfy214 Group TitleBest ResponseYou've already chosen the best response.0
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?
 11 months ago

AonZ Group TitleBest ResponseYou've already chosen the best response.0
yes thats correct
 11 months ago

ilfy214 Group TitleBest ResponseYou've already chosen the best response.0
But its a negative so \[4y \times 2y = 8y^2\]

ilfy214 Group TitleBest ResponseYou've already chosen the best response.0
But really from that link you posted, you can take out \[(x+2y3)\] From the this you can take out x \[3x^2 + 2xy  8x\] From this you can factor out 2y \[2xy  8y^2 +14y\] And lastly 3\[3\]

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

I guess you can I tried to find the greatest common factor in each, instead of reverse foil. Reverse FOIL is mostly for trinomials..
 11 months ago

AonZ Group TitleBest ResponseYou've already chosen the best response.0
mhm i tried that. Btw i never done reverse foil before so is there any other way?
 11 months ago

AonZ Group TitleBest ResponseYou've already chosen the best response.0
is it possible if you find the greatest common factor?

ilfy214 Group TitleBest ResponseYou've already chosen the best response.0
Yes. I just showed you... Also some methods are:  Number of Terms  Factor Out the GCF First  Reversing FOIL  Guess and Check

Its possible because that is what I did. For your x, you can factor out x ONLY because 3 is not a factor of 8. Also the lowest variable is x in all three. \[3x^2+2xy−8x\]

Also, this equation is an alternate form of your polynomial, not your polynomial factored out... Besides did you mean to write this instead?\[x (3 x+2 y8)+(148 y) y3\]

ilfy214 Group TitleBest ResponseYou've already chosen the best response.0
Its okay :)

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

AonZ Group TitleBest ResponseYou've already chosen the best response.0
not sure how...
 11 months ago

ilfy214 Group TitleBest ResponseYou've already chosen the best response.0
X, Y and your constant are separate cases. Like what I wrote if you scroll up.

ilfy214 Group TitleBest ResponseYou've already chosen the best response.0
Let me try again! Here is your GCF, right? \[(x+2y − 3)\] When it comes to your x variables, only x can be factored out since 3 is not a factor of 8 even thought 2 is. Also you can't factor out x^2 because each monomial does not x^2. They all have at least one. \[3x^2 + 2xy − 8x\] Also these monomials are the only ones with an "x"

still dont get how you got ur GCF...
 11 months ago

ilfy214 Group TitleBest ResponseYou've already chosen the best response.0
When it come to your y variables, you can factor out 2y because 2 is the greatest common factor. \[2xy−8y^2+14y\] And lastly for 3. It is the only constant. So when factoring, all you will use is (1) (3) \[−3\]

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

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

EXAMPLE: What are the factors and GCF for these numbers? 2  1, 2 3  1, 3 12  1, 2, 3, 4, 6, 12 The GCF for these is 1.
