if you wanted to you could just foil the answers till you get the one that matches what you are looking for
jennyrlz
  • jennyrlz
but instead we will solve it :D
anonymous
  • anonymous
ok ill try that
anonymous
  • anonymous
oh ok
jennyrlz
  • jennyrlz
x^2-x+6 to solve this you will need to make it into two parenthesis
jennyrlz
  • jennyrlz
to do this you need to make both parenthesis when multiplide equal the samething you started with, it will get easier to understand as i get into it
jennyrlz
  • jennyrlz
so we have ( , ) ( , ) blank parnthesis, so lets begin with the x^2 (x, ) (x, )
jennyrlz
  • jennyrlz
since we have 2 x's we can spead it evenly accross the parenthisis
jennyrlz
  • jennyrlz
next, here comes the tricky part
jennyrlz
  • jennyrlz
we need to distribute the 6
jennyrlz
  • jennyrlz
to do so we get 2 x 3
jennyrlz
  • jennyrlz
so for now we have (x, 2) (x,3)
jennyrlz
  • jennyrlz
now lets look at the signs
jennyrlz
  • jennyrlz
+ and -
jennyrlz
  • jennyrlz
meaning we need both plus and minus
jennyrlz
  • jennyrlz
so we can eliminate c
anonymous
  • anonymous
okay
jennyrlz
  • jennyrlz
oooooooooooooooooooooook
jennyrlz
  • jennyrlz
i didnt see the -
jennyrlz
  • jennyrlz
in front of x^2
jennyrlz
  • jennyrlz
ok the answer is A
jennyrlz
  • jennyrlz
let me explain
anonymous
  • anonymous
thank u so much btw for taking time to explain tho
jennyrlz
  • jennyrlz
-x^2-x+6 first before we seperate it we need to take out the negative in from of x^2 if we dont they will contradict later in the problem
jennyrlz
  • jennyrlz
to do this just take change all the sighns... in other words: -(x^2+x-6)
jennyrlz
  • jennyrlz
with me so far?
jennyrlz
  • jennyrlz
to do this just hange all the signs*
anonymous
  • anonymous
yes im sorry this website keeps crashing on me
jennyrlz
  • jennyrlz
anyways now we go back to where we were
jennyrlz
  • jennyrlz
-(x-2)(x+3)
jennyrlz
  • jennyrlz
understand :D
jennyrlz
  • jennyrlz
that is the answer xD
anonymous
  • anonymous
yes! :)
jennyrlz
  • jennyrlz
