x = 113, x = - 113

Dezimale

x = 10.63014 \dots, x = - 10.63014 \dots

Schritte zur Lösung

x^{2} = 7^{2} + 8^{2}

Vereinfache

7^{2} + 8^{2} : 113

Für

x^{2} = f (a)

sind die Lösungen

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

x = 113, x = - 113

\frac{1}{2} x^{2} - 2 x - 6 = 0

y + 1 = \frac{y ^{2} - 6}{2}

(1 - x)^{2} - 2 = 0

x^{2} - 49 = (x + 7)

2 a x^{2} - b x + a^{2} b^{2} = 0
