I'm trying to write a calculated question with multichoice options:
Calculate the following product $$(x+{={a}})(x+{={b}})$$
The problem is when writing the options, I just cant write the power, tried
$$pow(x,2)+{={a}+{b}}x+{={a}*{b}}$$
$$x^2+{={a}+{b}}x+{={a}*{b}}$$
$$x**2+{={a}+{b}}x+{={a}*{b}}$$
$$pow({x},2)+{={a}+{b}}x+{={a}*{b}}$$
All four return the same, for example the first one returns $$pow(x,2)+{={a}+{b}}x+{={a}*{b}}$$.
The values of a and b works fine
