x^2=a^2

Lösung

x^{2} = a^{2}

x = a, x = - a

Schritte zur Lösung

x^{2} = a^{2}

Für

x^{2} = f (a)

sind die Lösungen

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

x = a^{2}, x = - a^{2}

Vereinfache

a^{2} : a

Vereinfache

- a^{2} : - a

x = a, x = - a

t^{2} - 2 t - 15 = 0

12 e^{2} - 9 e = - 12

4 x^{2} - 16 = 48

so l v e f or x, 9 x^{2} + 12 x + 9 y^{2} - 6 y + 5 = 0

- 3 x^{2} + 2 x + 8 = 0
