#5.8 The Quadratic Formula

• (2-30) even
• put the Quadratic Formula to a song---you will be singing it in front of class for a grade (25 points). You can do it by yourself or with a friend. Your choice. I don't care if you use Pop Goes the Weasel (there is a link to the right -----------------------------------------------------------------------> if you want to practice to Pop Goes the Weasel) or Alicia Keys, whatever. You choose. I just want you to know the quadratic formula. And no, you will not be able to use a note card when you're singing. That would be defeating the purpose. Just in case you don't know the lyrics to your song, here they are (yes, I added a couple of words at the beginning):
• "x equals the opposite of b plus or minus the square root of b squared minus 4ac all over 2a"
• (32-38) even -- just copy these
• copy the definition of the Discriminant of a Quadratic Equation on pg. 287
• copy the green box on pg. 288
• copy the Summary orange box on pg. 289
• I will go over all of these things tomorrow. Just make sure you have them copied BEFORE coming into class!
