(x)(x)=49

Lösung

(x) (x) = 49

x = 7, x = - 7

Schritte zur Lösung

(x) (x) = 49

Vereinfache

x^{2} = 49

Für

x^{2} = f (a)

sind die Lösungen

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

x = 49, x = - 49

49 = 7

- 49 = - 7

x = 7, x = - 7

8 e^{2} + 4 e + 7 = 0

co m pl e t es q u a re 4 y^{2} + 24 y

3 m^{2} - 5 m + 2 = 0

15 x^{2} + x - 6 = 0

x^{2} + 10 x = 42
