x^2=9*4

Lösung

x^{2} = 9 \cdot 4

x = 6, x = - 6

Schritte zur Lösung

x^{2} = 9 \cdot 4

Multipliziere die Zahlen:

9 \cdot 4 = 36

x^{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

c^{2} = 1 5^{2} + 8^{2}

19 x - 6 x^{2} - 10 = 0

20 x^{2} + 33 x + 10 = 0

x^{2} + (x + 6)^{2} = (x + 12)^{2}

x = - \frac{1}{20} x^{2}
