a^2=17^2-8^2

Lösung

a^{2} = 1 7^{2} - 8^{2}

a = 15, a = - 15

Schritte zur Lösung

a^{2} = 1 7^{2} - 8^{2}

Vereinfache

1 7^{2} - 8^{2} : 225

Für

x^{2} = f (a)

sind die Lösungen

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

a = 225, a = - 225

225 = 15

- 225 = - 15

a = 15, a = - 15

x^{2} - 2 x + x^{2} - 4 x = 0

(t + 4)^{2} = 16

2 5^{2} = x^{2} + 2 0^{2}

5 m^{2} - 2 m = 6

a^{2} 3 = 3
