    How do you simplify [2/(x+4)]+2 ----------- [3/(x+4)]+1 I know the answer is 2(x+5)/(x+7), but I have little idea how to get there! Please help?! multiply your fraction by (x+4)/(x+4) you end up with [2 + 2(x+4)]/[3 + (x+4)] simplify and you will get your answer. oooooooh thanks!

    i know how to do the majority of these type of questions, but i don't know how to simplify this one all the way.. 8(2x-1)^3= 125 i know you could go (2x-1)^3= 125/8 (2x-1)^3= (5/2)^3 but how can i simplify any further, and yes there is an answer.
