solvefor y,y^2=4+4/9 x^2

Lösung

löse nach

y, y^{2} = 4 + \frac{4}{9} x^{2}

y = 4 + \frac{4}{9} x^{2}, y = - 4 + \frac{4}{9} x^{2}

Schritte zur Lösung

y^{2} = 4 + \frac{4}{9} x^{2}

Für

x^{2} = f (a)

sind die Lösungen

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

y = 4 + \frac{4}{9} x^{2}, y = - 4 + \frac{4}{9} x^{2}

5 x^{2} + 12 x + 5 = 0

- 27 xx = 1

2 x^{2} - x - 17 = - 5

7 x^{2} - 2 x - 7 = 0

2 x^{2} - 7 + 1 = 0
