b^2=77

Lösung

b^{2} = 77

b = 77, b = - 77

Dezimale

b = 8.77496 \dots, b = - 8.77496 \dots

Schritte zur Lösung

b^{2} = 77

Für

x^{2} = f (a)

sind die Lösungen

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

b = 77, b = - 77

5 x^{2} - 10 x = 23

- x^{2} - 4 x + 1 = - 2 x^{2}

so l v e f or x, x^{2} + 4 b = 0

co m pl e t es q u a re 2 x^{2} - 4 x + 11

9 x^{2} = 360
