x^2=28+72

Lösung

x^{2} = 28 + 72

x = 10, x = - 10

Schritte zur Lösung

x^{2} = 28 + 72

Addiere die Zahlen:

28 + 72 = 100

x^{2} = 100

Für

x^{2} = f (a)

sind die Lösungen

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

x = 100, x = - 100

100 = 10

- 100 = - 10

x = 10, x = - 10

f a c t or z^{2} + 8 z + 12

- 2 (3 x - 4) = 4 (x + 3) + 6

8 - \frac{1}{2} (x - 4)^{2} = 0

x^{2} + 16 x + 44 = 0

\frac{1}{27} = (\frac{1}{3})^{3}
