was ist (v-1)²+ (v+3)² = 2 v²-2

(v-1)² + (v+3)² = 2v² -2                                                                                                                          

v²-2v+1 +v²+6v+9 = 2v² -2

v² +v² -2v² -2v +6v  = -2-10

4v = -12

v = -3

Gruß radix !

Danke :) habe da solche probleme
