y^2=81

Lösung

y^{2} = 81

y = 9, y = - 9

Schritte zur Lösung

y^{2} = 81

Für

x^{2} = f (a)

sind die Lösungen

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

y = 81, y = - 81

81 = 9

- 81 = - 9

y = 9, y = - 9

f a c t or x^{4} - 3 x^{2} - 54

7 x = 6 x - 4

f a c t or 16 x^{3} - 4 x^{2}

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

f a c t or 12 y^{2} + 2 y - 2
