t^2=81

Lösung

t^{2} = 81

t = 9, t = - 9

Schritte zur Lösung

t^{2} = 81

Für

x^{2} = f (a)

sind die Lösungen

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

t = 81, t = - 81

81 = 9

- 81 = - 9

t = 9, t = - 9

t (13 - t) = 40

so l v e f or x, x^{2} + y^{2} - 6 x + 4 y + 13 = 0

co m pl e t es q u a re x^{2} + 6 x - 16 = 0

x^{2} + (m + 4) x + \frac{3 m}{2} + \frac{9}{2} = 0

so l v e f or x, x^{2} + 11 k x + 40 = 0
