Here is the data from the Quadratics Quiz through Completing the Square. In class we will review the mistakes made on #10 which most people lost 1 point on. #13 was meant to be tough and 43% correct would bear this out. Both the Quadratic Formula and Completing the Square work to solve for A<0. Guess and check is not a valid method.
I was a bit surprised about the results of #15. Many did not simplify the quadratic formula completely Square root of 88 can be simplified.
85% average, 87% median.
