Question 484646: Take any number (except for 1). Square that number and then subtract one. Divide by one less than your original number. Now subtract your original number. Did you reach 1 for an answer? You should have. How does this number game work? Hint: Redo the number game using a variable instead of an actual number and rewrite the problem as one rational expression. How did the number game use the skill of simplifying rational expressions? (Explain this process in detail)

x

--> x^2 - 1

--> (x^2 - 1)/(x - 1) = x + 1

--> 1

It works for all x not equal to 1. I'm sure you can figure out where you had to divide rational expressions...
