Gap-fill
Ask the student a question, and give any hints about how they should answer this part.
Use the quadratic formula to solve the following quadratic:
{{scoeff}x2+{lcoeff}x+{ccoeff}=0}.
x=
Note: Put the smallest value (the one with the negative in front of the square root) in the first gap.
Use this tab to check that this question works as expected.
