Answer:

There are 16 rows of seats in the auditorium.

Explanation:

Jose is correct in writing out 416 = 2x² - 6x.

Rewriting this in descending order by powers of x, we get:

2x² - 6x - 416 = 0

Dividing all four terms by 2 simplifies this equation to x² - 3x - 208 = 0. This equation, in turn, factors to (x + 13)(x - 16) = 0. The only reasonable answer is x = 16. Jose's solutions are incorrect.

There are 16 rows of seats in the auditorium.

The number of seats per row is 416/16, or 26.
