k(x)=(-2x-15)/(x+9),k(-6w)

Lösung

k (x) = \frac{- 2 x - 15}{x + 9}, k (- 6 w)

x = \frac{- 9 k - 2 + 81 k ^{2} - 24 k + 4}{2 k}, x = \frac{- 9 k - 2 - 81 k ^{2} - 24 k + 4}{2 k}; k \neq = 0

Schritte zur Lösung

k (x) = \frac{- 2 x - 15}{x + 9}

k x (x + 9) = - 2 x - 15 : x = \frac{- 9 k - 2 + 81 k ^{2} - 24 k + 4}{2 k}, x = \frac{- 9 k - 2 - 81 k ^{2} - 24 k + 4}{2 k}; k \neq = 0

x = \frac{- 9 k - 2 + 81 k ^{2} - 24 k + 4}{2 k}, x = \frac{- 9 k - 2 - 81 k ^{2} - 24 k + 4}{2 k}; k \neq = 0

\frac{x + 5}{x} = \frac{4}{5}

\frac{2}{p} + \frac{3}{p + 1} = 5

x = \frac{( x - 1 )}{( x - 1 )}

\frac{1}{x ^{2} + 10 x + 25} = 4

\frac{7}{2 - x} = 0
