A=(x^2+12x+35)/(x+3)

Lösung

A = \frac{x ^{2} + 12 x + 35}{x + 3}

x = \frac{- 12 + A + A ^{2} - 12 A + 4}{2}, x = \frac{- 12 + A - A ^{2} - 12 A + 4}{2}

Schritte zur Lösung

A = \frac{x ^{2} + 12 x + 35}{x + 3}

A (x + 3) = x^{2} + 12 x + 35

Löse

A (x + 3) = x^{2} + 12 x + 35 : x = \frac{- 12 + A + A ^{2} - 12 A + 4}{2}, x = \frac{- 12 + A - A ^{2} - 12 A + 4}{2}

x = \frac{- 12 + A + A ^{2} - 12 A + 4}{2}, x = \frac{- 12 + A - A ^{2} - 12 A + 4}{2}

\frac{2 x}{48} = \frac{3}{x}

x + \frac{2}{x} = \frac{9}{2}

\frac{9}{k ^{3}} = \frac{3}{5}

(\frac{a - 2}{3 a}) + 35 = 50

3 \cdot \frac{x}{x + 2200} = 0.8
