I shared this data on our quadratics quiz with students in class. Here are the results.
The biggest mistake was on # 12 and #16. Remember in factored form you must set each term equal to zero and solve.
The roots of y=(x-3)(x+2) are 3 and -2.
In both cases each factor is set equal to zero as in (2x-1)=0 and x+2=0.
Average was an 89% and median was a 91%.
