[3rd edition] Error in "Strategies for Identifying Conic Sections".

On the last page of Hyperbolas section is a summary of the whole chapter:

You skipped B coefficient, referring to future chapters, but then that it is the coefficient of y (in equation supposed to be C).  I'm referring to the third edition, chapter 7 (Hooked conics), section about Hyperbolas, last page before exercises (p540)
