Tolong jawab beserta caranya ya.... saya lg bth bgt

katakganteng -6m / n-5 + n-10 / m-5

samakan terlebih dahulu penyebutnya ..

-6m.(m-5) + (n-10)(n-5)
----------------------------------
(n-5)(m-5)

-6m²+30m + n² - 5n -10n +50
------------------------------------------
nm -5n -5m + 25

IcukSugiarto $\boxed{ \frac{-6m}{n-5}~+~ \frac{n-10}{m-5} }~~~~~~[samakan\ penyebutnya, sehingga]\\\\ \boxed{= \frac{-6m(m-5)}{(n-5)(m-5)}~+~ \frac{(n-10)(n-5)}{(n-5)(m-5)} } \\\\ \boxed{= \frac{-6m(m-5)+(n-10)(n-5)}{(n-5)(m-5)}} \\\\ \boxed{= \frac{-6m^{2}+30m+n^{2}-5n-10n+50}{mn-5n-5m+25}} \\\\ \boxed{= \frac{-6m^{2}+30m+n^{2}-15n+50}{mn-5n-5m+25}}$
