x^2=1^2+(1/2)^2

Lösung

x^{2} = 1^{2} + (\frac{1}{2})^{2}

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

Dezimale

x = 1.11803 \dots, x = - 1.11803 \dots

Schritte zur Lösung

x^{2} = 1^{2} + (\frac{1}{2})^{2}

Vereinfache

1^{2} + (\frac{1}{2})^{2} : \frac{5}{4}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{5}{4}, x = - \frac{5}{4}

\frac{5}{4} = \frac{5}{2}

- \frac{5}{4} = - \frac{5}{2}

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

60 = 50 + 2 t - 0.0625 t^{2}

- 4 x^{2} + 2 x - 5 = 0

6 x^{2} + 6 x = 1

(x - 5)^{2} - 2 = 79

- 400 (x)^{2} + 9600 x + 792000 = 0
