r^2=(-2)^2+(2sqrt(3))^2

Lösung

r^{2} = (- 2)^{2} + (23)^{2}

r = 4, r = - 4

Schritte zur Lösung

r^{2} = (- 2)^{2} + (23)^{2}

Vereinfache

(- 2)^{2} + (23)^{2} : 16

Für

x^{2} = f (a)

sind die Lösungen

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

r = 16, r = - 16

16 = 4

- 16 = - 4

r = 4, r = - 4

\frac{x ^{2}}{3} + 2 x = x

x^{2} + 20 x - 45 = (x - 4)^{2} - (x - 4)^{2}

w^{2} + 375 - 376 = 0

2 t^{2} - 9 t + 4 = 0

3 x^{2} + 27 x + 24 = 0
