HW # 4
Please read 7.1 and 7.2 carefully.
Please go to page pcc.edu/staff/wdiss/notes. Please read and copy into your notebook the notes for solving by using the quadratic formula and solving by using the square root property. These notes are under the topic Quadratic Equations.
Problems:
7.1: 3 – 30 by 3
7.2: 12 – 24 by 3
——————————————————–
HW # 5
NOTE: Different instructions on this assignment from the ones listed in the book.
7.2: 11 – 40.
- If a polynomial can be factored, solve by factoring.
- If the equation can be solved by the square root property, please use the square root method.
- If polynomial cannot be factored and if the equation cannot be set up to use square root method, then use the quadratic formula or complete the square.
- When using the quadratic formula or completing the square do 1/2 with one method and 1/2 with the other.
——————————————————–
HW # 6
Please read the notes from on Quadratic Functions at:
I have also included the links here:
Quadratic Functions
The notes on graphing are then very necessary to complete the following:
9.3: 33 – 36. Please do one per piece of graph paper.
If you do not have graph paper, you can print one up from this website.
http://www.printfreegraphpaper.com/gp/c-i-14.pdf
People are still having trouble with completing the square. You can look at the notes at for completing the square and for the other three methods we learned at:
I have also included the links here:
Quadratic Equations
- Solve by Factoring [pdf]
- Solve by Using Quadratic Formula [pdf]
- Solve by Using Square Root Property [pdf]
- Solve by Completing the Square [pdf]
Please solve the following by completing the square.
13.3: 17, 19, 26, 27
