Question

A rational expression has been simplified below.For what values of x are the two expressions equal?A.All real numbers except -4B.All real numbersC.All real numbers except -4 and 2D.All real numbers except 2

Answer 1

From the image:

$\frac{(x-4)(x-2)}{9(x-2)}=\frac{x-4}{9}$

All reall values of x except 2 will give us same result

This is because, 2 will make the RHS of the equation undefined.

Therefore, the correct answer is option D
