Best ResponseYou've already chosen the best response.0difference of 2 squares

Best ResponseYou've already chosen the best response.0This is a difference of squares: A^2B^2=(A+B)(AB) In this case, A=2x and B=3y So 4x^29y^2=(2x+3y)(2x3y)

Best ResponseYou've already chosen the best response.5Plug that in and get the answer, this is simple, you can doit yourself

Best ResponseYou've already chosen the best response.5and jim, guide them but don't post the answers, i think they should do it themselves.

Best ResponseYou've already chosen the best response.5What I mean is tell them what to do.

Best ResponseYou've already chosen the best response.0true, but I find it helps to step them through it

Best ResponseYou've already chosen the best response.09x^2+16 so how would id o this one

bahrom7893

Best ResponseYou've already chosen the best response.5Well jim we already factored a couple of problems. Like see what i mean, tell them to use this formula: a^2b^2 = (ab)(a+b) Tell them to observe that: 4x2  9y2 = (2x)^2(3y)^2, and tell them to do the substitution to factor.

Best ResponseYou've already chosen the best response.5Sarsar I don't think that's factorable.

Best ResponseYou've already chosen the best response.5Wait we can complete the square

jim_thompson5910

Best ResponseYou've already chosen the best response.0you can complete the square, but that won't make it factorable

Best ResponseYou've already chosen the best response.0how do u know if something is not factorablw

Best ResponseYou've already chosen the best response.5I think it can be factored

jim_thompson5910

Best ResponseYou've already chosen the best response.0if you have a sum of squares, then it is NOT factorable.

Best ResponseYou've already chosen the best response.0whats a sum of squares

Best ResponseYou've already chosen the best response.59x^2+16 (3x)^2 + 2*3x*4 + 4^2  2*3x*4

Best ResponseYou've already chosen the best response.0a square is any expression that can be represented by squaring another expression. For example, 4 is a square of 2 since 2 squared = 4 Also, 4x^2 = (2x)^2 is another square

Best ResponseYou've already chosen the best response.5And then: (3x+4sqrt(24x))(3x+4+sqrt(24x))

Best ResponseYou've already chosen the best response.5I mean that just makes it uglier haha

jim_thompson5910

Best ResponseYou've already chosen the best response.0but when they say "factorable", they mean over the rationals.

jim_thompson5910

Best ResponseYou've already chosen the best response.0and you forgot the imaginary terms, which makes it even worse

bahrom7893

Best ResponseYou've already chosen the best response.5oh i guess, i mean i never learned how u guys do it here in the US.

Best ResponseYou've already chosen the best response.0don't worry about it, 9x^2+16 is NOT factorable

Best ResponseYou've already chosen the best response.0how about this one 2xyxz+2wywz

bahrom7893

Best ResponseYou've already chosen the best response.5Okay sarsar observe what is similar in the equation

bahrom7893

Best ResponseYou've already chosen the best response.0i think u can do like this : 9x^2 +9+7 then we wil factor : 9(x^2+1)+7 then:( 9+7)(x^2+1)

Best ResponseYou've already chosen the best response.04ax + 8ay + 3bx + 6by so like in this one, do i start by taking out the GCF?

jim_thompson5910

Best ResponseYou've already chosen the best response.0sorry Roh, that's not the correct factorization. You can verify that by expanding

bahrom7893

Best ResponseYou've already chosen the best response.5no u pulled out 9+7, u can't do that

jim_thompson5910

Best ResponseYou've already chosen the best response.0first, group terms (4ax + 8ay) + (3bx + 6by)

jim_thompson5910

Best ResponseYou've already chosen the best response.0what comes next?

bahrom7893

Best ResponseYou've already chosen the best response.5Jim where did u get that one from?

bahrom7893

Best ResponseYou've already chosen the best response.5oh u just took it as an example? I see was talkin about this (4ax + 8ay) + (3bx + 6by)

Best ResponseYou've already chosen the best response.0ahhhhh im confused lol

bahrom7893

Best ResponseYou've already chosen the best response.5I think ima leave, having too much people to help confuses others

Roh

Best ResponseYou've already chosen the best response.0yoou can factor it by group factoring sarsar no confusing is needed let me do it

jim_thompson5910

Best ResponseYou've already chosen the best response.04ax + 8ay + 3bx + 6by (4ax + 8ay) + (3bx + 6by) 4a(x + 2y) + 3b(x + 2y) (4a+3b)(x + 2y)

sarsar56
 4 years ago
Best ResponseYou've already chosen the best response.04ax + 8ay + 3bx + 6by ok so u group the terms (4ax+8ay) (3bx+6by)

jim_thompson5910

Best ResponseYou've already chosen the best response.0first group the terms, then pull out the GCF from each group. From there, combine like terms.
