Lösung

b^{2} = 2

b = 2, b = - 2

Dezimale

b = 1.41421 \dots, b = - 1.41421 \dots

Schritte zur Lösung

b^{2} = 2

Für

x^{2} = f (a)

sind die Lösungen

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

b = 2, b = - 2

a x^{2} + b x + 7 = k (3 x^{2} - 2 x + 1)

((3 x)^{2} + (4 x)^{2}) - 4 x + 975 x = 5 x^{2}

x^{2} - 2 (k - 1) x + 6 k - 11 = 0

a^{2} + 2 1^{2} = 2 9^{2}

6 x^{2} + 8 x - 4 = 0
