x^2=9^2+40^2

Lösung

x^{2} = 9^{2} + 4 0^{2}

x = 41, x = - 41

Schritte zur Lösung

x^{2} = 9^{2} + 4 0^{2}

Vereinfache

9^{2} + 4 0^{2} : 1681

Für

x^{2} = f (a)

sind die Lösungen

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

x = 1681, x = - 1681

1681 = 41

- 1681 = - 41

x = 41, x = - 41

1.5 x^{2} - 6 x + 3 = 0

(x + 1)^{2} = 3 (x - 1)^{2}

x^{2} - 5 = 8 - 2 x^{2}

5 x (x - 2) = 6 + 3 x

so l v e f or x, x^{2} - 15 - m (2 x - 8) = 0
