9+16=x^2

Lösung

9 + 16 = x^{2}

x = 5, x = - 5

Schritte zur Lösung

9 + 16 = x^{2}

Tausche die Seiten

x^{2} = 9 + 16

Addiere die Zahlen:

9 + 16 = 25

x^{2} = 25

Für

x^{2} = f (a)

sind die Lösungen

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

x = 25, x = - 25

25 = 5

- 25 = - 5

x = 5, x = - 5

d = d^{1} - d^{2}

0.75 (0.25 - x + x^{2}) = x^{2}

a = 3 x^{2} - 9 x

so l v e f or x, z = x^{2} - 8 x y + 5 y + 7

a = 3 r^{2}
