%28%28b%5Ex%29%5E%28x-9%29%29%2F%28b%5E%289-x%29%29


%28b%5E%28x%28x-9%29%29%29%2F%28b%5E%289-x%29%29


b%5E%28x%28x-9%29-%289-x%29%29


b%5E%28x%5E2-9x-9%2Bx%29%5E%22%22


b%5E%28x%5E2-8x-9%29%5E%22%22


So %28%28b%5Ex%29%5E%28x-9%29%29%2F%28b%5E%289-x%29%29 simplifies to b%5E%28x%5E2-8x-9%29%5E%22%22


In other words, %28%28b%5Ex%29%5E%28x-9%29%29%2F%28b%5E%289-x%29%29=b%5E%28x%5E2-8x-9%29%5E%22%22 for all values of b and x, where b and x are positive.
