1. Haven't done this type of math in a long time, here's the question: 1. Rationalize the numerator a) (√x - 3) / (x - 9) Can't get the answer for the life of me. The textbook says (1)/(√x - 3) the / dictates division. 2. Relevant equations Question: (√x - 3) / (x - 9) Answer: (1)/(√x - 3) 3. The attempt at a solution I multiplied the top and bottom by the conjugate of the numerator (√x + 3) and ended up getting (x-9)/(x√x + 3x - 9√x - 27) and I get stumped here.
