Right you solved half part of the question and got 2x^2+36x....leave this for now...lets do the other part.. So, - x(4x - 2) What is -x*4x+x*2?? double negative=positive one negative,one positive=negative.
anonymous
  • anonymous
-4x +

anonymous
  • anonymous
hmmm 2x?
anonymous

That's right!

So, 2x^2+36x-4x^2+2x...Agree?
anonymous
  • anonymous
yes
anonymous
  • anonymous
:)
uri

Get all x^2 values together and x values together.
anonymous
  • anonymous
I don't get it... 2x^2 - 4x^2 36x + 2x is that what you mean?
uri
  • uri
Yes that's what i mean..Believe in yourself,hun.
uri

2x^2-4x^2=? 36x+2x=?
anonymous

2x^2 38x2
anonymous

oh, okay, now what?
anonymous
