Gap-fill
Ask the student a question, and give any hints about how they should answer this part.
Fill in the blanks to solve the quadratic by completing the square:
| {{scoeff}x2+{lcoeff}x+{ccoeff+c}} | = | {c} | |
| ⟹ | {{scoeff}x2+{lcoeff}x} | = | |
| ⟹ | x2+ |
= | |
| ⟹ | x2+ |
= | |
| ⟹ | (x+ |
= | |
| ⟹ | (x+ |
= | ± |
| ⟹ | x | = |
Note: In the last gap, if x=1,2, enter set(1,2).
