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 x²-5x-24 and the width to be x² + 5x + 6. Each cubby hole in the bookshelf will have a height of x + 2 and width of x - 8. Step 1 of 3: Write a rational expression to determine how many cubbies high the book shelf will be.
