A rectangular auditorium seats 1833 people. The number of seats in each row exceeds the number of rows by 8. Find the number of seats in each row.
Let x = number of rows.....then (x + 8) = the seats on each row
And we have that
x (x + 8) = 1833
x^2 + 8x - 1833 = 0 factor
(x - 39) (x + 47) = 0
Setting the frist factor to 0 is the only one that makes sense .....so......x - 39 = 0 → x = 39 = the number of rows
And the number of seats in each row is 8 more than this = 47
