2g(a)=(5x)/(x^2-9)

Lösung

2 g (a) = \frac{5 x}{x ^{2} - 9}

x = \frac{5 + 25 + 144 g ( a ) ^{2}}{4 g ( a )}, x = \frac{5 - 25 + 144 g ( a ) ^{2}}{4 g ( a )}; 2 g (a) \neq = 0

x^{2} - 9

2 g (a) (x^{2} - 9) = 5 x

Löse

2 g (a) (x^{2} - 9) = 5 x : x = \frac{5 + 25 + 144 g ( a ) ^{2}}{4 g ( a )}, x = \frac{5 - 25 + 144 g ( a ) ^{2}}{4 g ( a )}; 2 g (a) \neq = 0

x = \frac{5 + 25 + 144 g ( a ) ^{2}}{4 g ( a )}, x = \frac{5 - 25 + 144 g ( a ) ^{2}}{4 g ( a )}; 2 g (a) \neq = 0

x - \frac{6}{x} = 5

x = \frac{2 x + 8}{x}

\frac{x}{78 + 24 + x} = \frac{1}{3}

\frac{4 \cdot ( 12 + y )}{4 - 2 y} = 12
