## Bananas1234 one year ago Subtract: 3/n - 8/n^2

Ok all we do is cross multiply or just add them together and get what?

2. jim_thompson5910

|dw:1433379845397:dw|

3. jim_thompson5910

Multiply top and bottom of 3/n by n. This is done so the n in the first denominator becomes n^2 |dw:1433379886041:dw|

4. jim_thompson5910

after that we will have |dw:1433379904705:dw| and I'll let you take over

5. Bananas1234

3n - 8/ n^2

6. jim_thompson5910
