Assignment #1

In Mr. Clark's first lecture, he mentioned an important concept. That concept was to make the inequality equation equal to zero. This will make the equation easier to solve, since you don't know what x is. So, you solve for x. First, you make a positive/negative number line graph for each factor in the equation. For example, (x-3)/ (x+5) < 0; the first number line will be for the factor, (x-3). Then you figure out what substracted by 3 will equal 0, so you get 3. You plot the number 3. The numbers after 3 will be positive and the numbers before 3 will be negative. You do the same for the other factor. Then you draw the lines to find the sections that are less than 0. So you get -5< x <3.
