\(\frac{2}{6}-\frac{n+1}{2n+3}\)

I'm trying so hard to do these but I just can't >.<

Using my method cited on your other post

 

The first fraction reduces to    1 / 3

 

So we have

 

1        -     n + 1

__         ______

3           2n + 3

 

Cross-multiply in this order    1 (2n + 3)   - 3(n + 1)  ⇒ 2n + 3 - 3n - 3  ⇒ -n

 

Multiply the denominators

3 ( 2n + 3)   =   6n + 9

 

So...we have

 

  -n

_____             and you are finished  !!!!

6n + 9 

 

 

 

 

cool cool cool
