Can someone help me with this? Simplify the rational expressions. State any excluded values. Show your work. 3x-6/x-2 3x-6/x-2 =2x+3 <--- is this right?

Okay so to simplify factor out 2 from the equation in the numerator.

And to state the excluded values, just make the denominator not equal to 0.
anonymous
  • anonymous
I messed up i was suppose to make my 3 negative and like always i for got haha
anonymous
  • anonymous
So what is the simplified form of the expression?
anonymous
  • anonymous
x3
anonymous
  • anonymous
x-3
anonymous
  • anonymous
Hmm no.
anonymous
  • anonymous
|dw:1437949548153:dw|
anonymous
  • anonymous
Do you know how to factor?
anonymous
  • anonymous
Don't think i can factor 3 any lower unless i make it 1
anonymous
  • anonymous
Sigh.|dw:1437949769605:dw|
anonymous
  • anonymous
You're correct that it will 1. :)
anonymous
  • anonymous
will be*
anonymous
  • anonymous
Alright, do i add the 3's to get six how did you get six if not
anonymous
  • anonymous
No multiply them again to get 3x-6.
anonymous
  • anonymous
|dw:1437949902336:dw|
anonymous
  • anonymous
Now, you're not yet done with it because you still simplify it.
anonymous
  • anonymous
Alright.
anonymous
  • anonymous
|dw:1437949978179:dw|
anonymous
  • anonymous
Are you there?
anonymous
  • anonymous
Yeah i'm here
anonymous
  • anonymous
So what's the answer now?
anonymous
  • anonymous
3x?
anonymous
  • anonymous
no
anonymous
  • anonymous
|dw:1437950117617:dw|
anonymous
  • anonymous
I'll give you an example.
anonymous
  • anonymous
I thought x-2/x-2 = 0
anonymous
  • anonymous
|dw:1437950158254:dw|
anonymous
  • anonymous
No. :(
anonymous
  • anonymous
I already gave you an example. So what's the answer now? :)
anonymous
  • anonymous
so it would be 3?
anonymous
  • anonymous
Yes! :D
anonymous
  • anonymous
For the excluded values...
anonymous
  • anonymous
Make the denominator NOT equal to 0.
anonymous
  • anonymous
Do you know where the denominator is?
anonymous
  • anonymous
The lower number example 5/7 <-- denominator
anonymous
  • anonymous
So what is the denominator of the expression?
anonymous
  • anonymous
x-2?
anonymous
  • anonymous
Right so...|dw:1437950496073:dw|
anonymous
  • anonymous
Just do it algebraically.
anonymous
  • anonymous
x?
anonymous
  • anonymous
|dw:1437950539642:dw|
anonymous
  • anonymous
+2
anonymous
  • anonymous
Huh?
anonymous
  • anonymous
|dw:1437950594256:dw|
anonymous
  • anonymous
x2?
anonymous
  • anonymous
What?!
anonymous
  • anonymous
I'll give you an example.
anonymous
  • anonymous
....
anonymous
  • anonymous
|dw:1437950639765:dw|
anonymous
  • anonymous
??????????????
anonymous
  • anonymous
Looks like it's going to be x2 but clearly it's not so i'm clueless.
anonymous
  • anonymous
I can't make the unequal mark. x unequal 2?
LynFran
  • LynFran
correct so x not equal 2 is the restricted value
anonymous
  • anonymous
Thanks Lynn
anonymous
  • anonymous
Thanks Lynn.
