Week One of your online course, in the “Introduction to ALEKS” section, you will see an Adobe Captivate presentation on a mathematical program called ALEKS. This program is extremely important in this course. Your assignment for this discussion is to watch all the short video clips in the module (these videos can be seen by clicking on the tabs located at the bottom of the video screen). After you introduce yourself to your fellow classmates, please explain what one of the videos in the module taught you about how to use the ALEKS system. Now that you have seen a little bit about what lies ahead, please explain your primary worries or excitements about this course. If you do not feel comfortable sharing your feelings, please explain what you hope to get out of the course. Week 1 - Discussion 1010 unread replies.1010 replies.

22x + 11
− 3x − 10

x2

In the real number system division by zero not defined. Therefore, if there some values that make
the denominator zero, then the function is not defined in that x values. In this case we need to set
the denominator equal to zero to find the excluded values that makes the denominator “zero”
x 2 − 3x − 10 = 0
Factorizing the polynomial
(x − 5)(x + 2) = 0
Setting each factor zero
(x ...
