Alright so the way I was taught to do factors like this was first multiply the first term by the last term so 2*6=12

  • anonymous
Now we have to find something that multiplys to equal twelve and adds to equal -7

The cross method is easier

um, -4 and -3? @recon14193

yes so what we can do is split up the center term now. It's not correct by normal math standards but when we're done you will have it factored

See?

so we have \[2x^{2}-3x-4x+6\]
anonymous
  • anonymous
then we group them and factor from each
anonymous
  • anonymous
So it becomes (2x-3)(x-2)
anonymous
  • anonymous
so is (2x-3)(x-2) the final answer?
anonymous
  • anonymous
Correct

If you see the attachments

You will be able to see the cross method applied

okay, then why are my answer choices: a. 2 b. y − 8 c. x − 4 d. x + 6

  • anonymous
Huh... That's weird

Can you send a pic?

That's very odd because non of those answers are factored
anonymous
  • anonymous
so what would be the right answer out of those?
anonymous
  • anonymous
I'm so confused...
anonymous
  • anonymous
Well non of them are correct
anonymous
  • anonymous
Is there a way to contact your teacher about that?
anonymous
  • anonymous
unfortunately not
anonymous
  • anonymous
If not... Just pick one because the expression you have me can be put into a quadratic equation and when that is true you can never have just a variable and a number
anonymous
  • anonymous
oh okay. well thanks for your help anyway :)
anonymous
  • anonymous
Sure thing... Non of the choices are correct so you shouldn't get penalized for it... I mean factored means to have two separate items to multiply with
