The first few steps in solving the quadratic equation 8x2 + 80x = −5 by completing the square are shown.

8x2 + 80x = −5

8(x2 + 10x) = −5

8(x2 + 10x + 25) = −5 +

which number is missing in the last step?

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.
