Упростите выражение: (m-(14m-49)/m)/(7/m-1).

\[\frac{m^{\backslash m} - \frac{14m - 49}{m}}{\frac{7}{m} - 1^{\backslash m}} =\]

\[= \frac{\frac{m^{2} - 14m + 49}{m}}{\frac{7 - m}{m}} =\]

\[= \frac{\frac{(m - 7)^{2}}{m}}{\frac{- (m - 7)}{m}} =\]

\[= \frac{(m - 7)^{2}}{m}\ :\frac{- (m - 7)}{m} =\]

\[= 7 - m\]
