solvefor x,x^2=y^2+4z^2

Lösung

löse nach

x, x^{2} = y^{2} + 4 z^{2}

x = y^{2} + 4 z^{2}, x = - y^{2} + 4 z^{2}

Schritte zur Lösung

x^{2} = y^{2} + 4 z^{2}

Für

x^{2} = f (a)

sind die Lösungen

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

x = y^{2} + 4 z^{2}, x = - y^{2} + 4 z^{2}

2 x^{2} + 12 x = - 3

8 x^{2} + 13 x - 6 = 0

so l v e f or x, y = x^{2} - 4 x

(x - 7)^{2} = 15

j (x) = - 2 x^{2} + 8 x - 9
