Question

Simplificati raportul algebric,astfel incit sa se obtina un raport algebric ireductibil
y²minus x²\x²minus yx

Answer 1

(y²-x²)/(x²-yx)=
=(y+x)(y-x)/(-x)(-x+y)=
=(y+x)(y-x/(-x)(y-x)=
=(y+x)/(-x)=-y/x-1

Answer 2

(y²-x²)/(x²-yx)= =(y+x)(y-x)/(-x)(-x+y)= =(y+x)(y-x/(-x)(y-x)= =(y+x)/(-x)=-y/x-1
