Hallo,
\( -\frac{5 x}{4-x}-\frac{2 x}{48-3 x^{2}}= \)
\( -\frac{5 x}{4-x}-\frac{2 x}{3(16- x^{2})}= \)
\( -\frac{5 x}{4-x}-\frac{2 x}{3(4-x)*(4+x))}= \) |1. Bruch 3*(4+x) erweitern
\( -\frac{5 x*3(4+x)}{3*(4-x)*(4+x)}-\frac{2 x}{3(4-x)*(4+x)}= \)
\( -\frac{60x+15x^2}{3*(4-x)*(4+x)}-\frac{2 x}{3(4-x)*(4+x)}= \) | Zähler zusammenfassen
\( \frac{-62x-15x^2}{3*(4-x)*(4+x)}= \)
