anonymous · Answer

The first one is factored by grouping, I am confused on the 2nd. :D

anonymous · Answer

I think...HELP!!!

anonymous · Answer

yes it can
take out the 3m from the first part and 7 from the second

anonymous · Answer

Ok, thx. :)

anonymous · Answer

you get 3m(m+2n)+7(m+2n)

anonymous · Answer

then you can simplify it as (3m+7)(m+2n)

anonymous · Answer

good enough?

anonymous · Answer

Hmm...yes, can you show me the first one to make sure?

anonymous · Answer

a.4x2 + 12xy + 2x + 2y

anonymous · Answer

yeah....im not so sure about the first one...i dont think you can do it by group factoring because it can't be factored unless done by completing the square or using the quadratic formula

anonymous · Answer

wait...you did learn about breaking it up into 3 and 1 or 2 and 2 right?

anonymous · Answer

Yes, I really don't understand this!!! I hate math and science. :(

anonymous · Answer

lol, I'm not a big fan either, but im pretty sure you cant do the first one, let me look it up

anonymous · Answer

yeah..you can't

anonymous · Answer

Oh, wow, lol! Then what do I say?

anonymous · Answer

they will all have to become a diff of squares to be solvable for the first one

anonymous · Answer

A. cannot be factored by grouping
B. can

anonymous · Answer

Oh, lol! Thx!! :D totally think this stuff is hard!!

anonymous · Answer

Now I need the other one aboutr Jose. :)
