Ok, I have a basic understanding of how to do these, sorta, but I need someone to walk me through how do do EACH of these promblems.
OK the first:
1.
(x-1)(x+2)(x-4)(5x-6) > 0
2.
(x-1)^3(2x+3)(x-5) < 0
3.
(x-10)^2(x+6)(3x-9)(2x+12) > 0

One way to do these would be to sketch the graph of (x-1),(x+2),(x-4),(5x-6). you can easily see when each bracket is positive or negative on the graph, so you can see which areas of the number line would have a positive product of four values and which a negative product. The first bracket is a line of slope 1 which passes through zero when x is 1 This is not only as easy as doing it analytically, you are less likely to make a mistake if you can see the picture in front of you.
