divide; simplify the results 2x+4 divided by 4x ----- --- x-2 x^2-4

Dividing by a fraction is the same as multiplying by its reciprocal...so... |dw:1349655907653:dw|

OpenStudy (anonymous):

And then multiply across like you would with any fraction

OpenStudy (anonymous):

perfect, thank you for the effort :)

OpenStudy (anonymous):

Anytime! :] Good luck and have fun~

doublecook, one thing... do you realize you flipped the 4x over x^2-4?

OpenStudy (anonymous):

Yup, that was the point! When you divide a fraction by another fraction, you flip the second fraction and multiply

OpenStudy (anonymous):

So (a/b)/(c/d)=(ad/bc)
