Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$\displaystyle \simplify{Limit((x + { -a}) / (x ^ 2 + { -a -b} * x + {a * b}),x,{a}) }=\;$ Unnamed gap (input as a fraction or as an integer).

Advice

Note that on putting $x=\var{a}$ into $\displaystyle \simplify{(x + { -a}) / (x ^ 2 + { -a -b} * x + {a * b}) }$ we get a $0/0$ case and so we have to do more work.

You can factorise $\simplify{x ^ 2 + { -a -b} * x + {a * b}}$ and then see what happens.

Give a worked solution to the whole question.
