h^2=40^2-30^2

Lösung

h^{2} = 4 0^{2} - 3 0^{2}

h = 107, h = - 107

Dezimale

h = 26.45751 \dots, h = - 26.45751 \dots

Schritte zur Lösung

h^{2} = 4 0^{2} - 3 0^{2}

Vereinfache

4 0^{2} - 3 0^{2} : 700

Für

x^{2} = f (a)

sind die Lösungen

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

h = 700, h = - 700

700 = 107

- 700 = - 107

h = 107, h = - 107

3 x^{2} + 26 x + 35 = 0

n^{2} - n - 2 = 0

co m pl e t es q u a re 3 x^{2} + 4 x + 5

16 x^{2} - 34 = 15

f^{2} = 49
