A rectangle has sides of 5x-12 and 5x+12.
--------------
What is the area of the rectangle?
(5x-12)(5x+12) = 25x^2-144 sq units
-------------------------
Inside the rectangle two squares with sides of x and x are to be removed. What is the remaining area of the rectangle?
--------------
Area of the two squares = x^2 + x^2 = 2x^2
Remaining area = 25x^2-144 -(2x^2)
= 23x^2-144
