I believe this quiz answer is incorrect. The question is:
‘How many values can be represented by variable x in the equation (x−2)(x+4)=0?’
The provided answer is 2 values, namely ‘2’ and ‘-4’. I believe it should be 3 values, since ‘0’ is another value that the variable x can take. I tried uploading an image below as well. Please correct me if I’m wrong.
The question is #2 out of 4 in the Variables section of Module 4, Part 1, of the I’m Overwhelmed Study Plan.
Thanks.
