Thread: [Help] Multiplying and Dividing Rational Expressions

Alright, I wanted to check and see if I got my answer right to this following question..



I came up with x over 3x+4

Thanks

Factorise both fractions to get

(x+4)(x-4)/(x-4) X x/3(x+4)

I then simplified to get x/3

change divide into times by flipping the second term



now factor the top of the first term using difference of 2 squares and the bottom of the second term by taking out a common factor



now times the 2 terms together you get



and cancelling out terms
