x^2=3+2sqrt(2)

Lösung

x^{2} = 3 + 22

Lösung

x = 2 + 1

+1

Dezimale

x = 2.41421 \dots

Schritte zur Lösung

x^{2} = 3 + 22

Für

x^{2} = f (a)

sind die Lösungen

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

x = 3 + 22, x = - 3 + 22

3 + 22 = 2 + 1

- 3 + 22 = 2 + 1

x = 2 + 1

solvefor y,y^2+a^2=(a+y)2-a(a+1)

so l v e f or y, y^{2} + a^{2} = (a + y) 2 - a (a + 1)

a=(2x+1)2-(2x-1)2-(2-x)(2+x)-(x+1)2+5

a = (2 x + 1) 2 - (2 x - 1) 2 - (2 - x) (2 + x) - (x + 1) 2 + 5
