Best ResponseYou've already chosen the best response.0x^2  16 / 4x + (x  4)

Best ResponseYou've already chosen the best response.0and the options are : x + 4 / 4x x + 1/ x x  4 / x

Best ResponseYou've already chosen the best response.0is it\[{x^2  16 \over 4x} + (x4)\]

Best ResponseYou've already chosen the best response.0the lowest common denominator is 4x, so you just find the equivalent form of x4\[4x(x4) \over 4x\]

Best ResponseYou've already chosen the best response.0so when you simplify it, \[{x^2+4x^2 16x 16 \over 4x } ={ 5x^216x 16 \over 4x}\]

Best ResponseYou've already chosen the best response.0Ohh so you factor the numerator and then they cancel out? >.< i think i might be confused ^^

Best ResponseYou've already chosen the best response.0I don't think the problem is right. because the rational form only goes this much and even if you do long division you still don't get any answer from the choices you gave

Best ResponseYou've already chosen the best response.0Ya thats why i was stumped >.< but those are the exact answers they gave me

Best ResponseYou've already chosen the best response.0Hmmm alright my teacher says to divide so will you help me with dividing them? (:

anonymous

Best ResponseYou've already chosen the best response.0I am thinking that the problem is actually \[{x^216 \over 4x(x4)}\]

Best ResponseYou've already chosen the best response.0No it isnt i wish it was >.< my teacher said it was a typo and ur suppossed to divide... :P go figure lol

Best ResponseYou've already chosen the best response.0hmm, this one would be (x+4)/4x = 1/4 +1/x

anonymous

Best ResponseYou've already chosen the best response.0okay, then let's just do long division

anonymous

Best ResponseYou've already chosen the best response.0can be written as follows \[{x \over 4}  {4 \over x}\] by long division

Best ResponseYou've already chosen the best response.0Wait so then it would have to be A or C right?

anonymous

Best ResponseYou've already chosen the best response.0when you add x4 you will get \[{x \over 4}  {4 \over x} +x4\]

Best ResponseYou've already chosen the best response.0you can't go further if you make it into one big fraction, it's the one with the 5x^2

Best ResponseYou've already chosen the best response.0Hmmm thats so strange!! why are all my problems like that!:P

anonymous

Best ResponseYou've already chosen the best response.0even if you work from the answers none of them match for example x + 4/x = \[x^2 +4 \over x\] so it's not the answer

Best ResponseYou've already chosen the best response.0>.< That is frackin frustrating :P lol i gave u a medal tho cuz at least u tried (:

Best ResponseYou've already chosen the best response.0So then for the problem : 10a^2/7b^2 / 25a^3/14b^3 what would be the answer? (:

anonymous

Best ResponseYou've already chosen the best response.0let's work one by one the rational expression can be written as such by making a division into a multiplication and taking the reciprocal \[{10a^2 \over 7b^2}*{14b^3 \over 25 a^3}\]

anonymous

Best ResponseYou've already chosen the best response.0now this is a lot easier, the a's b's can cancel and 10 and 25 have something in common etc..

anonymous

Best ResponseYou've already chosen the best response.0you will end up having \[2b \over 5a\]

Best ResponseYou've already chosen the best response.0ohhhh ya i just did that whole problem after u said u dont long divide im such a frickin blonde lol thanks!! i asked for help when i didnt even need it... figures :P lol

Best ResponseYou've already chosen the best response.0Ok i am retaking an assignment and i will prolly be checking or asking for help on here do you think you can help? (: or will ay least be on .... ?(:

Best ResponseYou've already chosen the best response.0unfortunately I need to go :( Good luck though. My advise is to take each step slowly 1), find LCD 2), make all rationals equivalent form with the LCD 3), add the numerators 4), once simplified, check if it factors 5), check if there is anything in common with the denominator also, keep the denominator factored, because it would be an extra step to expand it
