bahrom7893Best ResponseYou've already chosen the best response.5
okay use this formula: a^2b^2=(ab)(a+b)

difference of 2 squares
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
This 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)

Plug that in and get the answer, this is simple, you can doit yourself

bahrom7893Best ResponseYou've already chosen the best response.5
and jim, guide them but don't post the answers, i think they should do it themselves.

What I mean is tell them what to do.

i really wish i understood all of this lol

true, but I find it helps to step them through it

sarsar56, you will need this in your future life.

if not sarsar, let me know

9x^2+16 so how would id o this one
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
Well 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.

bahrom7893Best ResponseYou've already chosen the best response.5
Sarsar I don't think that's factorable.
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
Wait we can complete the square
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
you can complete the square, but that won't make it factorable
 2 years ago

sarsar56Best ResponseYou've already chosen the best response.0
how do u know if something is not factorablw
 2 years ago

RohBest ResponseYou've already chosen the best response.0
thi will be like this (3x+4)(3x4)
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
I think it can be factored
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
if you have a sum of squares, then it is NOT factorable.

sarsar56Best ResponseYou've already chosen the best response.0
whats a sum of squares
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
9x^2+16 (3x)^2 + 2*3x*4 + 4^2  2*3x*4
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
a 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

RohBest ResponseYou've already chosen the best response.0
ouch i am sorry i thought there is minuse so sorry!!!

bahrom7893Best ResponseYou've already chosen the best response.5
And then: (3x+4sqrt(24x))(3x+4+sqrt(24x))
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
I mean that just makes it uglier haha
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
but when they say "factorable", they mean over the rationals.
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
and you forgot the imaginary terms, which makes it even worse
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
oh i guess, i mean i never learned how u guys do it here in the US.
 2 years ago

sarsar56Best ResponseYou've already chosen the best response.0
i kind of see it but not really ):
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
don't worry about it, 9x^2+16 is NOT factorable
 2 years ago

sarsar56Best ResponseYou've already chosen the best response.0
how about this one 2xyxz+2wywz
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
Okay sarsar observe what is similar in the equation
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
2xyxz+2wywz 2xy+2wyxzwz 2y(x+w)z(x+w)
 2 years ago

RohBest ResponseYou've already chosen the best response.0
i 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)
 2 years ago

sarsar56Best ResponseYou've already chosen the best response.0
4ax + 8ay + 3bx + 6by so like in this one, do i start by taking out the GCF?
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
sorry Roh, that's not the correct factorization. You can verify that by expanding
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
no u pulled out 9+7, u can't do that
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
first, group terms (4ax + 8ay) + (3bx + 6by)
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
what comes next?
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
Jim where did u get that one from?
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
oh u just took it as an example? I see was talkin about this (4ax + 8ay) + (3bx + 6by)
 2 years ago

sarsar56Best ResponseYou've already chosen the best response.0
ahhhhh im confused lol
 2 years ago

bahrom7893Best ResponseYou've already chosen the best response.5
I think ima leave, having too much people to help confuses others
 2 years ago

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

jim_thompson5910Best ResponseYou've already chosen the best response.0
4ax + 8ay + 3bx + 6by (4ax + 8ay) + (3bx + 6by) 4a(x + 2y) + 3b(x + 2y) (4a+3b)(x + 2y)
 2 years ago

sarsar56Best ResponseYou've already chosen the best response.0
4ax + 8ay + 3bx + 6by ok so u group the terms (4ax+8ay) (3bx+6by)
 2 years ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
first group the terms, then pull out the GCF from each group. From there, combine like terms.
 2 years ago

RohBest ResponseYou've already chosen the best response.0
4a(x+2y)+3b(x+2y) (x+2y)(4a+3b)
