b^2=16

Lösung

b^{2} = 16

b = 4, b = - 4

Schritte zur Lösung

b^{2} = 16

Für

x^{2} = f (a)

sind die Lösungen

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

b = 16, b = - 16

16 = 4

- 16 = - 4

b = 4, b = - 4

x^{2} - 28 x + 147 = 0

x^{2} + 10 + 25 = 0

(2 x - 5) (2 x + 5) - 119 = 0

x^{2} - 10 x + 28 = 0

so l v e f or y, y^{2} = x^{2}
