<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the number of rows.  Then *[tex \Large x\ +\ 3] must be the number of seats in a row.  The total number of seats is the product of the number of rows and the number of seats in a row:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x^2\ +\ 3x\ =\ 270]


Solve for the positive root of the quadratic.
