Question

5м-9/м-2 - 3-2м/2-м упростите выражения

Answer 1

$frac{5m-9}{m-2} - frac{3-2m}{2-m}= frac{5m-9+3-2m}{m-2}= frac{3m-6}{m-2}= frac{3(m-2)}{m-2}=3$

Answer 2

$frac{5m-9}{m-2} - frac{3-2m}{2-m} = frac{5m-9}{m-2} + frac{3-2m}{m-2}= frac{5m-9+3-2m}{m-2} = frac{3m-6}{m-2} = frac{3(m-2)}{m-2} = \ = frac{3*1}{1} =3$
