Erik is building a cubby bookshelf, that is, a book shelf divided into storage holes (cubbies) instead of shelves. He wants the height of the bookshelf to be x^2 - 11x - 12 and the width to be x^2 + 3x + 2. Each cubby hole in the bookshelf will have a height of x + 2 and of width of x - 12. Multiply the rational expressions from Step 1 and Step 2 to obtain a rational expression that gives the total number of cubbies in the entire bookshelf.
