What is x supposed to represent?
A picture frame has a square picture in the center of the frame, the top and bottom borders are each 2 inches wide and the left and right borders are each 4 inches wide. What is the value of x if the total area of the picture frame is 65.25 inches

The two x's inside the center frame
just subtract the picture area from the total, and that is the area of the frame:
(x+2*2)(x+2*4)-x^2 = 65.25
(x+2*2)(x+2*4)-x^2 = 65.25
