    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?
