Example: determine the zeroes of following polynomials.
P ( x)= 5x5 - 20x4+5x3 + 50x2 - 20x - 40 = 5 (x + 1)2 ( x - 2)3
Solution
In this the factoring has been done for us. Do not worries regarding factoring anything like this? You won't be asked to perform any factoring of this type anywhere in this material. There are only here to make the point that the zero factor property works here as well.
In this case we do have a product of 3 terms however the first is a constant and will not make the polynomial zero. So, from the last two terms it looks like the polynomial will be zero for x = -1 and x =2 .Thus, the zeroes of this polynomial are, x = -1 & x = 2
Linear Systems with Three Variables It is going to be a fairly short section in the sense that it's actually only going to contain a couple of examples to show how to take the

Interval notation The next topic that we have to discuss is the idea of interval notation. Interval notation is some very pleasant shorthand for inequalities & will be utilize
