Question

I need help with rational equations

Answer 1

me too:-)

Answer 2

so you don't know how to do them,?

Answer 3

Dunno, post one, let me see...

Answer 4

1/x+1 - 2/x-1 = 3

Answer 5

Yup, I can do that, what's the problem u r having?

Answer 6

i don't know how to do it

Answer 7

Do u know lcd?

Answer 8

lowest common denominator

Answer 9

That a no?

Answer 10

last chance, speak or forever...

Answer 11

1/x+1 - 2/x-1 = 3 | * x
<=> 1 + x - 2 - x = 3x
<=> x-x -3x = 1
<=> 3x=-1
<=> x=-1/3

Answer 12

thank you newm1, you are the best

Answer 13

Oh, so now u know how to do them, good.

Answer 14

thanks to newm1, yes

Answer 15

Better give newm1 a medal, then....

Answer 16

U click the button "Good answer" next to his reply...

Answer 17

No?, I will give him one on your behalf...

Answer 18

Did you mean
\[\frac{1}{x+1}-\frac{2}{x-1}= 3\]

Answer 19

Gave the solution to the given equation. Good point phi. Its hard when someone don´t use brackets.

Answer 20

Newm1, I know you did it right, but it sure looks strange to post an equation with a +1 and a -1 which obviously cancel.

So meg.. did you leave out the parenthesis Did you mean
1/(x+1) - 2/(x-1) =3

Answer 21

Answer's still right....

Answer 22

True, but there is another answer x=0. And the real point is to understand how to solve these. Are you going to take her test?

Answer 23

She claimed she now understood them...

Answer 24

The fact she clearly doesn't is entirely besides the point.
