the first problem you have x 7x - 8 ------ + -------- 8x 8x
ivettef365
  • ivettef365
whta is the common denominator

ivettef365
  • ivettef365
ok then you have x + 7x - 8 ---------- 8x
anonymous
  • anonymous
ok so my answer would be |dw:1371232193752:dw|
ivettef365
  • ivettef365
no you can do that
ivettef365
  • ivettef365
not do that
ivettef365
  • ivettef365
then you have 8x - 8 ------ 8x
ivettef365
  • ivettef365
you can take out the 8 8(x-1) ------ 8x
ivettef365
  • ivettef365
now you can cancel the 8 and you have x - 1 ----- x
ivettef365
  • ivettef365
which is the same as 1 - 1/x
anonymous
  • anonymous
ohhh ok wb #2
anonymous
  • anonymous
what would i do ther because they dont have common denominators
ivettef365
  • ivettef365
the second problem you have 4 1 ----- + ------- x-7 x-3
ivettef365
  • ivettef365
What is the common denominator ??
anonymous
  • anonymous
x?
ivettef365
  • ivettef365
no, actually you have to take the hold thing so the common denominator would be (x-7)(x-3)
anonymous
  • anonymous
ohh
ivettef365
  • ivettef365
so now what you do is 4 (x-3) + 1 (x-7) --------------- (x-3)(x-7)
anonymous
  • anonymous
ok then u would have |dw:1371232713526:dw|
ivettef365
  • ivettef365
no, you need to first multiply 4(x-3) and then 1(x-7)
ivettef365
  • ivettef365
then you have 4x - 12 + x - 7 -------------- (x-3)(x-7)
ivettef365
  • ivettef365
now combine like terms
anonymous
  • anonymous
|dw:1371232864645:dw|
anonymous
  • anonymous
would that be the answer?
anonymous
  • anonymous
invettef365 u still there?
ivettef365
  • ivettef365
yes that is correct
anonymous
  • anonymous
ok ty hate to do this but i only got one more problem on my HW could u help me out with it?
ivettef365
  • ivettef365
no actually it is 5x - 19 -------- (x-3)(x-7)
ivettef365
  • ivettef365
sure
anonymous
  • anonymous
ty simplify (x+1/x^2)+(3/4x)
ivettef365
  • ivettef365
ok, you have x + 1 3 ------- + -------- x^2 4x
ivettef365
  • ivettef365
what is the common denominator??
anonymous
  • anonymous
(x^2)(4x)
ivettef365
  • ivettef365
actually it is 4x^2
anonymous
  • anonymous
:( i hate fractions
ivettef365
  • ivettef365
because you can divide as follows: 4x^2 4x^2 ---- = x and ------ = 4x 4x x
ivettef365
  • ivettef365
sorry I meant 4x^2 ----- = 4 x^2
anonymous
  • anonymous
its ok
ivettef365
  • ivettef365
then you have 4(x+1) + 3(x) ------------- 4x^2
ivettef365
  • ivettef365
do you understand how I got there?
anonymous
  • anonymous
yea sort of
ivettef365
  • ivettef365
since 4x^2/x^2 = 4 I multiply 4 (x+1) and since 4x^2/4x = x I multiply 3(x)
anonymous
  • anonymous
ok i got it
ivettef365
  • ivettef365
know multiply 4(x+1) and 3(x) what do you get
anonymous
  • anonymous
4x+4+3x=7x+4
ivettef365
  • ivettef365
right then you have 7x +4 ------ 4x^2
anonymous
  • anonymous
ty so much invette
ivettef365
  • ivettef365
yw :)
