c^2=16+25

Lösung

c^{2} = 16 + 25

c = 41, c = - 41

Dezimale

c = 6.40312 \dots, c = - 6.40312 \dots

Schritte zur Lösung

c^{2} = 16 + 25

Addiere die Zahlen:

16 + 25 = 41

c^{2} = 41

Für

x^{2} = f (a)

sind die Lösungen

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

c = 41, c = - 41

20 + 12 v^{2} - 40 = - 10 v^{2} + 80 + 18 v^{2}

2 x^{2} + 8 x = - 32

2 x^{2} + 3 x - 560 = 0

x^{2} - 3 x - 2 = - 4

2 (x + 1)^{2} + 7 = 1
