ОДЗ x≠1
(x/(x-1))²=a
a²-3a+2=0
a1+a2=3 U a1*a2=2
a1=1⇒(x/(x-1))²=1
[x/(x-1)=-1⇒x=-x+1⇒2x=1⇒x=0,5
[x/(x-1)=1⇒x=x-1⇒0=-1 нет решения
a2=2⇒(x/(x-1))²=2
[x/(x-1)=-√2⇒x=-√2x+√2⇒x(1+√2)=√2⇒x=√2/(1+√2)=√2(1-√2)/(-1)=√2(√2-1)
[x/(x-1)=√2⇒x=√2x-√2⇒x(1-√2)=-√2⇒x=√2/(√2-1)=√2(√2+1)
Произведение корней 0,5*√2(√2-1)*√2(√2+1)=1
