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

I think...HELP!!!

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

Ok, thx. :)

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

good enough?

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

a.4x2 + 12xy + 2x + 2y
anonymous
  • anonymous
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
  • anonymous
wait...you did learn about breaking it up into 3 and 1 or 2 and 2 right?
anonymous
  • anonymous
Yes, I really don't understand this!!! I hate math and science. :(
anonymous
  • anonymous
lol, I'm not a big fan either, but im pretty sure you cant do the first one, let me look it up
anonymous
  • anonymous
yeah..you can't
anonymous
  • anonymous
Oh, wow, lol! Then what do I say?
anonymous
  • anonymous
they will all have to become a diff of squares to be solvable for the first one
anonymous
  • anonymous
A. cannot be factored by grouping B. can

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