x^{2} = 8^{2} + 2^{2}

x = 217, x = - 217

Dezimale

x = 8.24621 \dots, x = - 8.24621 \dots

Schritte zur Lösung

x^{2} = 8^{2} + 2^{2}

Vereinfache

8^{2} + 2^{2} : 68

Für

x^{2} = f (a)

sind die Lösungen

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

x = 68, x = - 68

68 = 217

- 68 = - 217

x = 217, x = - 217

2 x^{2} = 5 x + 42

3 y^{2} + 8 y - 3 = 0

q u a d r a t i c f or m u l a x^{2} - x + 1 = 0

x - x^{2} = - x - 7

x^{2} - 40 = - 6 x
