x^2=5^2+12^2

Lösung

x^{2} = 5^{2} + 1 2^{2}

x = 13, x = - 13

Schritte zur Lösung

x^{2} = 5^{2} + 1 2^{2}

Vereinfache

5^{2} + 1 2^{2} : 169

Für

x^{2} = f (a)

sind die Lösungen

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

x = 169, x = - 169

169 = 13

- 169 = - 13

x = 13, x = - 13

x^{2} - 289 = 0

4 (x + 7)^{2} - 49 = - 13

x^{2} - 6 x + 9 = 256

x^{2} = 7 x - 12

x^{2} - 2 x - 168 = 0
