GeoGebra Lesson

For this portion of the lesson, you will have the opportunity to explore how to solve one-variable quadratic equations. This activity will present you with several questions that you will have 15 minutes to work on. I will be monitoring the room so raise your hand if you have a question!

1. In written math language, how would you go about solving the following problem: [math]x^2=4[/math] ?

For the previous problem, what does x equal?

1 4 2 -2

2. The area of a square ABCD is 36 [math]ft^2[/math] and each side length is equal to [math]x[/math]. How would you determine what x is equal to?

Use the space below to create the square described in the previous problem. Leave yourself some space so that you can also solve the problem and show your work.

3. In written math language, how would you go about solving the following problem: [math]x^2+2x-8[/math] ? Are there any methods that you know of?

Use the space below to show your work for the previous problem.

4. CHALLENGE (If you have time):

Solve [math]2x^2+5x+3=0[/math]
