Algebra II (5) Assessment Reflection #4 (Quadratics)

November 21, 2012

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.  

My Best,

Patrick Morrissey
