thats an expression, not an equation :) that can be simplified. try multiplying x to each term in numerator and denominator
can you please draw it out ?
why is it x ? how do i rationalize the denominator ?
we're just simplifying the expression, unless we know whether x is rational or not, we can't say whether denominator is rational or not... why is it x?? i see 1/x in the expression, to simplify it, i wanted to multiply it with x but then i need to multiply everything with x to balance things out
i get that part. but why does it multiply by x ?
ah okay. i thought i had to simplify the whole denominator
are there any similar problems like that one ?
need any more help with this question ?
yes. so we multiply x because its missing an x ? on top and bottom ?
yes it was an expression .
i have to plug in f(x) and g(x) but i did that step
does the order matter ? the answer is 1+x/x+4
Order does matter, if the problem is as I wrote it, that is the fraction 1/(x + 1) is divided by the fraction 1/(x+4) you invert the divisor and proceed as is multiplication, Doing this results in what I have posted.
ah okay. Thank you !!!
