A rectangular auditorium seats 1920 people. The number of seats in each row exceeds the number of rows by 8. Find the number of seats in each row.

number of rows  x
number of seats per row  x+8
x(x+8) = 1920
x^2 + 8x  1920 = 0
(x40)(x+48)=0
x = 40 or x = 48, which of course makes no sense
there are 40 rows, and each row has 48 seats
