3/19/2017 -- Advanced: Quadratic equations, part 5. (Oleg Gleizer)

We will start with refreshing problem 18 from the 2/12 handout. http://www.math.ucla.edu/~radko/circles/lib/data/Handout-1272-1283.pdf We will then use the derived formula as a tool to solve Problems 19 and 20. Then we will finish the handout and proceed to the next one.
