    For each picture of work, the work is followed by the student's results on the entire test and the results of the first quiz for that student.
    The work of some students is missing. My fault. I either didn't take a picture of their paper of lost in in file transfer.
 

Yellow, Blue, & Green Answers

Student Work Sorted by Points Earned, then Correct Work and Errors
12 -- Full Credit         d
10 -- Missing Check on One Root         g
8 -- Found and checked one wrong root         c
8 -- Did Not Find Roots Correctly         d b
8 -- Omited +/- So found and checked only one root         a
8 -- No Written Checks         b e e h a
6 -- Isolated Radical, Indicated Squared Both Sides, Squared Correctly         g
6 -- Two Roots, Not One, No Checks of Roots         b c a
6 -- Didn't Find Both Roots, No Checks of Roots         f h
6 -- Successfully Squared Both Sides, No Roots, No Checks         de1 de2
6 -- Successfully Squared Both Sides, Then Stuff or Stopped         m q i j k i l jk1 m c
6 -- Almost Squared Both Sides, Almost Factored &Solved, Did Check Roots         f
5 -- Did Not Successfully Squared Both Sides, Then Stopped         h
5 -- Successfully Squared Both Sides, Then Equation Became Expression         n
4 -- Almost Successfully Squared Both Sides, Then Equation Became Expression         o
2 -- Isolated Radical, Indicated Decision to Square, Didn't Get Quadratic Correct         l
2 -- Did Not Successfully Squared Both Sides         jk1
1 -- Correctly Subtracted Term from Each Side to Isolate the Radical         jk2 l
0 -- Ignored the Radical, And Then Stuff         n p r pq1
0 -- Squared or Almost Squared Each Term on Each Side of the Equation         g mn2
0 -- Decided to Square Each Side of the Equation         o mn1 pq2
0 -- Almost Squared Each Side of the Equation         i
0 -- Did Nothing, Left the Problem Blank        p o jk2
