It is called the FOIL method. First, Outside, Inside, Last. Multiply What would be 4x and 4x then 4x and -7 and 4x and -7 and combine them then multiply - 7 and -7. You get a trinomial. Any questions?
anonymous
  • anonymous
awesome, thank you so much can i ask you one more question?
anonymous
  • anonymous
yes
anonymous
  • anonymous
(x^2=2x-35)/(x=7)
anonymous
  • anonymous
is that a fraction or division?
anonymous
  • anonymous
division, sorry.
anonymous
  • anonymous
i am not too sure exactly what you are asking sorrry
anonymous
  • anonymous
i just dont understand what i have to do to get the answer im confused
anonymous
  • anonymous
you need to find x^2?
anonymous
  • anonymous
no i just have to perform the division (x^2+2x-35)\[\div\]
anonymous
  • anonymous
(x+7)
anonymous
  • anonymous
there is a change in the problem....you originally had equal signs..... I am confused sorry.
anonymous
  • anonymous
ohh im sorry on my mac the equal and plus sign is the same button the last way i wrote it is correct im so sorry
anonymous
  • anonymous
to get it straight sorry..... (x^2+2x-35)รท (x+7)
anonymous
  • anonymous
exactly
anonymous
  • anonymous
ok give me a minute
anonymous
  • anonymous
k
anonymous
  • anonymous
working it out
anonymous
  • anonymous
ok u still here? U are going to have to reverse foil
anonymous
  • anonymous
im here
anonymous
  • anonymous
huh?
anonymous
  • anonymous
first step is (x+7)(x-5) Divided by (x+7) you get the two parenthesses if you FOIL those like before ypou get the original problem
anonymous
  • anonymous
im confused
anonymous
  • anonymous
okay remember how i showed you FOIL?
anonymous
  • anonymous
yes
anonymous
  • anonymous
im still getting confused when i try to divide it out
anonymous
  • anonymous
i see okay. You are in what grade if i may ask?
anonymous
  • anonymous
im in college, but this is the class before my college algebra class. i tested into it, im in honors everything else and beginners math hahahaha
anonymous
  • anonymous
ha being in Advanced Algebra 1 in 8th grade we learned this this year sorry having some small trouble. Going to figure it out though.
anonymous
  • anonymous
thank you so much, im trying my best and it is just frustrating im a college sophmore doing freshman in hs work
anonymous
  • anonymous
yeah i understand. Not from a personal perspective but you know.
anonymous
  • anonymous
how do i solve it?
anonymous
  • anonymous
ok going to go backwards it took me a while but i have figured out an example to show you . Divide x^2+2x-3 by x-1 it is similar
anonymous
  • anonymous
x-1 (inside division box is the next trinomial) x^2+2x-3 Okay?
anonymous
  • anonymous
okay
anonymous
  • anonymous
Ok so you will divide it out like a normal "long division problem"
anonymous
  • anonymous
ohh okayy, that makes it a tad clearer
anonymous
  • anonymous
okay Think: x^2 Divided by x=? Multiply x and x-1 Subtract x^2-x from x^2+2x Okay?
anonymous
  • anonymous
okay hold on im doing it ill send you my answer hold on
anonymous
  • anonymous
okay
anonymous
  • anonymous
i tried to work it out and typed it in my math way and it says there is no answer, did you get an answer?
anonymous
  • anonymous
the answer to the whole problem is x+3
anonymous
  • anonymous
how did you get that? im confused
anonymous
  • anonymous
Well i gave u step 1. U should get x x-1(Box)x^2+2x-3 x^2-3 3x
anonymous
  • anonymous
what is box?
anonymous
  • anonymous
sorry CPU is slow. A division box like for long division
anonymous
  • anonymous
..............
anonymous
  • anonymous
sorry if i could not help. Good bye
