x^2=sqrt(225)+(sqrt(81))+(2^3+sqrt(16))

Lösung

x^{2} = 225 + (81) + (2^{3} + 16)

x = 6, x = - 6

Schritte zur Lösung

x^{2} = 225 + (81) + (2^{3} + 16)

Vereinfache

225 + (81) + (2^{3} + 16) : 36

Für

x^{2} = f (a)

sind die Lösungen

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

x = 36, x = - 36

36 = 6

- 36 = - 6

x = 6, x = - 6

- 5 x^{2} - 100 x - 320 = 0

3 x - 2 x^{2} = 7

2 d^{2} + 11 d + 20 = d^{2}

6 (x - 1)^{2} + 15 = 105

(3 x + 3)^{2} = 16
