its f-g

oh so 3x--2x^2-2x
dan815
  • dan815
ya
dan815
  • dan815
simplify it
anonymous
  • anonymous
so 3x+2x^2-2x 2x^2+x

yep good

what????@Jhannybean is 2x^2+x wrong?
anonymous

(3x) - (-2x^2-2x)
anonymous
  • anonymous
(3x) - (-2x^2-2x)=2x^2+5x right?
Jhannybean
  • Jhannybean
Actually,this is what i got. \[f(x) = 3x \]\[g(x) = -2x^2-2x\]\[(f-g)(x)\]\[\large 3x - [-2x^2 - 2x]\]\[3x + 2x^2 + 2x \]\[2x^2 + 5x\]

  • bahrom7893
i believe so
Jhannybean
  • Jhannybean
yep, you're right xD
Jhannybean
  • Jhannybean
you did it wrong the first time, you got \(2x^2 +x \) as your answer.
