x^2=(-5)/2

Lösung

x^{2} = \frac{- 5}{2}

x = \frac{5}{2} i, x = - \frac{5}{2} i

Schritte zur Lösung

x^{2} = \frac{- 5}{2}

Wende Bruchregel an:

\frac{- a}{b} = - \frac{a}{b}

x^{2} = - \frac{5}{2}

Für

x^{2} = f (a)

sind die Lösungen

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

x = - \frac{5}{2}, x = - - \frac{5}{2}

- \frac{5}{2} = \frac{5}{2} i

- - \frac{5}{2} = - \frac{5}{2} i

x = \frac{5}{2} i, x = - \frac{5}{2} i

d^{2} - 1 = 0

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

so l v e f or x, x^{2} - 3 k x + 9 = 0

so l v e f or x, x^{2} + 3 x y + y^{2} = 1

5 x^{2} + 28 x - 2 = 7 x - 6
