r^2=(60)^2+(-11)^2

Lösung

r^{2} = (60)^{2} + (- 11)^{2}

r = 61, r = - 61

Schritte zur Lösung

r^{2} = (60)^{2} + (- 11)^{2}

Vereinfache

6 0^{2} + (- 11)^{2} : 3721

Für

x^{2} = f (a)

sind die Lösungen

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

r = 3721, r = - 3721

3721 = 61

- 3721 = - 61

r = 61, r = - 61

(k + 5)^{2} = 0

3 x^{2} - 8 x - 23 = - 4 x - 9

4 x^{2} + 6 x - 13 = 3 x^{2}

0 = 2 y - y^{2}

so l v e f or x, 0 = x^{2}
