x^2=12^2+5^2

Lösung

x^{2} = 1 2^{2} + 5^{2}

x = 13, x = - 13

Schritte zur Lösung

x^{2} = 1 2^{2} + 5^{2}

Vereinfache

1 2^{2} + 5^{2} : 169

Für

x^{2} = f (a)

sind die Lösungen

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

x = 169, x = - 169

169 = 13

- 169 = - 13

x = 13, x = - 13

11 x = x^{2} + 28

(3 x + 3)^{2} - 42 = - 39

co m pl e t es q u a re 4 x^{2} - 8 x

so l v e f or x, U = \frac{1}{2} k x^{2}

3 x^{2} - 12 x = - 27
