you solve this question

Answer 1

your answer would be =
x-4/x-3

Answer 2

➡HERE IS YOUR ANSWER⬇

$\frac{ {x}^{2} - 7x + 12 }{ {x}^{2} - 9} \\ \\ = \frac{ {x}^{2} - 4x - 3x + 12}{( {x})^{2} - ( {3})^{2} } \\ \\ = \frac{x(x - 4) - 3(x - 4)}{(x + 3)(x - 3)} \\ \\ = \frac{(x - 4)(x - 3)}{(x + 3)(x - 3)} \\ \\ = \frac{x - 4}{x + 3}$
