x^2=13^2-5^2

Lösung

x^{2} = 1 3^{2} - 5^{2}

x = 12, x = - 12

Schritte zur Lösung

x^{2} = 1 3^{2} - 5^{2}

Vereinfache

1 3^{2} - 5^{2} : 144

Für

x^{2} = f (a)

sind die Lösungen

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

x = 144, x = - 144

144 = 12

- 144 = - 12

x = 12, x = - 12

9^{2} + 1 3^{2} = x^{2}

8 - 3 t = 5 t^{2}

x^{2} - 1.8 x - 4.95 = 0

3 x^{2} + x - 12 = 0

x^{2} - 8 x + 16 = 9
