x^2=10^2-8^2

Lösung

x^{2} = 1 0^{2} - 8^{2}

x = 6, x = - 6

Schritte zur Lösung

x^{2} = 1 0^{2} - 8^{2}

Vereinfache

1 0^{2} - 8^{2} : 36

Für

x^{2} = f (a)

sind die Lösungen

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

x = 36, x = - 36

36 = 6

- 36 = - 6

x = 6, x = - 6

4 x^{2} - x - 3 = 3

2 x^{2} + 3 x + 3 = 4

co m pl e t es q u a re x^{2} + 6 x - 8

3 x^{2} - 60 x = - 249

- 2 x^{2} + x + 15 = 0
