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.

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36

It says factor each expression 49x-28?
