I don't know how to solve inequalities. I can manage with simple ones by using interval method but talking about fraction inequalities I am confused.

According to the attachment I got zero points {0;0;1;1;3;-2}. What's next ?

By factoring and according to the degree I started from left and from top drawing the graph because the counter x^4 (which is above denominator) is positive. But the following... two 0 and two 1 and the denominator.

I hope you understand what I want to know. So how to draw the full graph and how to write the answer in math terms.
