Best ResponseYou've already chosen the best response.0express the numerator as \[\frac{ x+11}{x+1} = \frac{ x+1}{x+1} + \frac{1}{x+1} = 1 \frac{1}{x+1} \]

Best ResponseYou've already chosen the best response.0\[1 \frac{1}{x+1}\] that should be last part

Best ResponseYou've already chosen the best response.0we add and subtract the same thing, so we dont change the value overall

Best ResponseYou've already chosen the best response.0can you give me another example?

Best ResponseYou've already chosen the best response.0take \[\frac{x+2}{x+3} \]

Best ResponseYou've already chosen the best response.0so we look on the bottom , it has x+3 , so we want to see an x+3 in the numerator

Best ResponseYou've already chosen the best response.0so express as \[\frac{x+3+2 3 }{x+3} = \frac{x+3 1 }{x+3}\]

Best ResponseYou've already chosen the best response.0\[= \frac{x+3}{x+3}  \frac{1}{x+3} = 1  \frac{1}{x+3}\]

Best ResponseYou've already chosen the best response.0its all fairly standard

Best ResponseYou've already chosen the best response.0so you mean I have to look at the bottom. if I have for example (x+4), then I have to add and substract 4 and 4 respectively?

Best ResponseYou've already chosen the best response.0yes , all it relys on is being able to split up the numerators

Best ResponseYou've already chosen the best response.0\[x/(1+x^{2})\]well i dont know what to do here :(

Best ResponseYou've already chosen the best response.0thats why it only works with linear terms in the numerator and denominator

Best ResponseYou've already chosen the best response.0or you could have something like \[\frac{x^2 +2x} {(x+1)^2} \]

Best ResponseYou've already chosen the best response.0So how should I do in cases like this. that is why I dont understand The oiginal problems starts there

Best ResponseYou've already chosen the best response.0the question is badly written, I would just ignore it, it cant be broken down further , teacher is stupid

Best ResponseYou've already chosen the best response.0Sorry dude but im working with integrals. They have an expression like that and get that answer. the answer is 11(x2 +1)

Best ResponseYou've already chosen the best response.0but if you want \[\int\limits \frac{x}{1+x^2} dx \]

Best ResponseYou've already chosen the best response.0in a book im reading, they say that \[x ^{2}/(1+x ^{2})=11/(1+x ^{2})\]

Best ResponseYou've already chosen the best response.0add and subtract 1 on the top and bottom

Best ResponseYou've already chosen the best response.0\[=\frac{x^2+11}{x^2+1} = \frac{x^2+1}{x^2+1}  \frac{1}{x^2+1} = 1 \frac{1}{x^2+1}\]
