how to graph this in the number line? (x^2 + 2)/(x^2+16)>0
this is a polynomial it will be on a coordinate plane
but this is inequality ? so how?
sorry forgot how , and i dont want to give wrong answer
do you know how to factor
just factor the top polynomial and then the bottom see if you can cancel any thing out
what i did was to factor both the numerator and the denominator i got an imaginary root/solution so how can i plot it in the number line..?? and 1 more thing, the denominator should not be equal to zero so that the inequality won't be undefined.. so x should not be equal to -4 and 4 , right?
if thats not good maybe im doing it the wrong way D:
i can not help you there i really can not deal with immaginary numbers
ok, that's fine.. thanks :)
