Some quadratics, SIMPLE QUADRATICS, can be solved by simply using our Algebra skills.
Using the following notes, students will analyze and understand how to find a simple square root.
Students should be able to demonstrate all examples in our notes and also explain for which quadratics can you use this method: 7.5.A Solving simple quadratics using sq roots.notebook
1. What is this method? What previous skill are we going to use?
2. What must the quadratic equation look like in order to use this method to solve?
3. What are some common mistakes we might make?
Homework for tomorrow is: Solving quadratics with square roots 2017.pdf

2. To review for your quiz on Tuesday, please complete the packet that is handed out to your group. Group solving by factoring, quadratic formula, and graphing!.docx :
In table groups have one person each solve YOUR quadratic equation using (no matter how many are in your table group, you should answer all papers given):
a. Factoring
b. Quadratic Formula
c. Graphing
d. If possible, use Simple Quadratics to solve - all group members decide/answer this
ALL YOUR ANSWERS SHOULD BE THE SAME IN YOUR TABLE GROUP!!
Be prepared to present your answers to the class TOMORROW!
a. show factored equation set = to 0 and answer
b. Show a = #, b = #, c = # and final answer
c. Show value for vertex and a rough graph and where the solutions are
d. show all steps to solving it as a Simple Quadratic, if possible.
e. SIGN YOUR NAMES ON THE PAPERS AND STAPLE YOUR 3 SHEETS TOGETHER. PLEASE PUT THEM IN MY MAILBOX.
