x^2+(-12/13)^2=1

Lösung

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

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

Dezimale

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

Schritte zur Lösung

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

Schreibe

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

um:

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

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

1000000 = 100000 + 1200 x + 200 x^{2}

so l v e f or x, x^{2} + y^{2} - 2 x + 2 = 0

k^{2} + 16 k - 17 = 0

x^{2} = 6^{2} + 4^{2}

2.5 \cdot 1 0^{- 9} = (0.072 - x) \cdot (0.04 - x)
