The video at the top of the page will show some examples similar to the ones I showed in class. It is important to remember you cannot cancel anything that is being added or subtracted, the factor or term must be multiplied in order for it to be cancelled. Most of the work in these types of problems will be finding common factors and factoring quadratic expressions. There are yet more examples here. Finally, if you want to quiz yourself, try some here and see if you can do them correctly.

3/8 Pre Algebra Extra Credit (Last Chance)

2 extra credit opportunities before 3rd quarter grades are final:

1) Visit this link, play around with the endpoints (you can just click and drag in the picture), and give me a half page write up of things that you discovered or found out.

2) Draw a segment in the coordinate plane (two endpoints). Calculate the distance between the 2 points. Then make a right triangle with the segment as the hypotenuse. Do the Pythagorean Theorem to find the lenght of the hypotenuse. Show your work and explain what you notice about doing the distance formula and doing the Pythagorean Theorem.

5 points per & you can do both.
