3. Let’s review completing the square

4. Try a couple more…

5. What about applications?
If you have 30 feet of fencing, what is the maximum area of space that you can enclose?

6. What about applications? Take 1 whiteboard and 2 markers per group

40m by 110m

7. Want to see a different way?
Check this video out!
