SUMMARY
The forum discussion centers on a mathematical problem regarding the distance from a fixed point, specifically point O. The user presents the equation +(2a-b)-(3a+2b) and concludes that the answer should be -a-3b. However, they express confusion over a textbook's answer of a+b, suggesting it may be a typographical error. The consensus among participants supports the user's calculation, reinforcing the likelihood of an error in the textbook.
