Question

3/x - 3/x-1- 3/x-2? can someone please show me how to do this step by step please?

Answer 1

its supposed to be rational expressions o.O

Answer 2

-3(x+1)/x

Answer 3

1) Please be careful with parenthesis

I assume you mean:
3/(x) - 3(x-1) - 3/(x-2)

2) Please be specific with your question...

I assume you mean:
"
Express 3/(x) - 3(x-1) - 3/(x-2) as a single fraction.
"

Answer 4

There are LOTS of examples here (scroll down to example 3 for problems exactly like this one) :)

Answer 5

there were no paranthesis in the problem :(

Answer 6

I'm guessing it was written as \[ \large \frac{3}{x}+\frac{3}{x-1}+\frac{3}{x-2}\]

But when you write it in plain text you have to put whatever is in the denominator in a set of parenthesis.

Answer 7

yes! and ohh okay
