    I'm having trouble getting my head around how to draw some of the graphs, the solving bit I'm fine with but I don't understand some things.

    For example:

    \frac{1}{3x^2-x-2}< 0

    Wtf?

    Also, when I'm given a question such as...

    \frac{x+3}{x-1} < \frac{x-3}{x+1}

    First of all, how do I know how to draw a graph like this, how will the numerator/denominator manipulate its shape?

    Is it better to draw them both out and then graphically solve. If yes, when I'm trying to find the points of intersection will I always have to make one side = 0 and then draw a seperate graph out for that? I don't understand how you can just move over values and make one graph out of two.. Sorry if you don't get it I'm not being as clear as I may have liked..

    hi! =) Is it from "Heinemann modular mathematics Pure Mathematics C4"? Exercise 1A?=) You don't need to use graph method here, should use numerical like in "Example 2" of that book=)
