Best ResponseYou've already chosen the best response.0Sorry, 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.

Best ResponseYou've already chosen the best response.0for some reason i cant factorise this question :/ i dont see taking out these common factors to be any help...

Best ResponseYou've already chosen the best response.0i 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

Best ResponseYou've already chosen the best response.0REVERSE FOIL Starting with 3x^2 and 8y^2, what can they be factored into?

Best ResponseYou've already chosen the best response.03 and 1, x and x 2 and 4, y and y

Best ResponseYou've already chosen the best response.0\[3x \times x = 3x^2\]\[2y \times 4y = 8y^2\] Is that not correct?

ilfy214

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

Best ResponseYou've already chosen the best response.0But 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\[3\]

Best ResponseYou've already chosen the best response.0...."you can factor out"....

Best ResponseYou've already chosen the best response.0I guess you can I tried to find the greatest common factor in each, instead of reverse foil. Reverse FOIL is mostly for trinomials..

Best ResponseYou've already chosen the best response.0mhm i tried that. Btw i never done reverse foil before so is there any other way?

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

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

Best ResponseYou've already chosen the best response.0Its 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. \[3x^2+2xy−8x\]

Best ResponseYou've already chosen the best response.0you forgot to completely factor out \[( 8x^2  14y)\]

Best ResponseYou've already chosen the best response.0Also, 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

Best ResponseYou've already chosen the best response.0Lets try this again! Take out your GCF from your polynomial.... \[3x^2 +2xy  8y^2  8x +14y  3\]

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

Best ResponseYou've already chosen the best response.0Let 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"

Best ResponseYou've already chosen the best response.0still dont get how you got ur GCF...

Best ResponseYou've already chosen the best response.0When 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) \[−3\]

Best ResponseYou've already chosen the best response.0Do you know what the term GCF is? GREATEST COMMON FACTOR

Best ResponseYou've already chosen the best response.0EXAMPLE: 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.
