Typo?

[Tylenol]

Posting here because I couldn't find a week 2 challenge subcategory.

Anyways, for question 10 when you square (a+b)/2 the bottom doesn't appear to be squared until the next step(4ab).

@tylenol Thanks so much for noticing this typo! I've fixed this now. I really appreciate your help, and I hope you're having a good time with the course.
