x^2=12^2+9^2

Lösung

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

x = 15, x = - 15

Schritte zur Lösung

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

Vereinfache

1 2^{2} + 9^{2} : 225

Für

x^{2} = f (a)

sind die Lösungen

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

x = 225, x = - 225

225 = 15

- 225 = - 15

x = 15, x = - 15

4 x^{2} = - 10 x + 14

- 2 x^{2} + 3 x - 9 = 0

y^{2} + 4 y + 5 = 3

x^{2} = 225 + (81) + (2^{3} + 16)

- 5 x^{2} - 100 x - 320 = 0
