Lösung

y^{2} = 28

y = 27, y = - 27

Dezimale

y = 5.29150 \dots, y = - 5.29150 \dots

Schritte zur Lösung

y^{2} = 28

Für

x^{2} = f (a)

sind die Lösungen

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

y = 28, y = - 28

28 = 27

- 28 = - 27

y = 27, y = - 27

3 x^{2} - 23 x + 30 = 0

x^{2} + 72 = - 17 x

f a c t or x^{2} - 2 x + 1 = 4

16 x^{2} - 80 x = 0

x^{2} - 20 x = - 64
