Lösung

(- \frac{12}{13})^{2} + x^{2} = 1

x = \frac{5}{13}, x = - \frac{5}{13}

Dezimale

x = 0.38461 \dots, x = - 0.38461 \dots

Schritte zur Lösung

(- \frac{12}{13})^{2} + x^{2} = 1

Schreibe

(- \frac{12}{13})^{2} + x^{2}

um:

\frac{144}{169} + x^{2}

\frac{144}{169} + x^{2} = 1

Verschiebe

\frac{144}{169}

auf die rechte Seite

x^{2} = 1 - \frac{144}{169}

Vereinfache

1 - \frac{144}{169} : \frac{25}{169}

Für

x^{2} = f (a)

sind die Lösungen

x = f (a), - f (a)

x = \frac{25}{169}, x = - \frac{25}{169}

\frac{25}{169} = \frac{5}{13}

- \frac{25}{169} = - \frac{5}{13}

x = \frac{5}{13}, x = - \frac{5}{13}

\frac{1}{2} x^{2} + 7 x = 0

x^{2} - 3 x - 44 = - 3 x + 5 - 3 x + 5

so l v e f or y, x^{4} - 7 x y^{2} + y = 7

x^{2} + (\frac{5}{13})^{2} = 1

so l v e f or x, f = 3 x^{2} + 2 y + 5
