解方程:(x^2+1)(y^2+1)=10 (x+y)(xy-1)=3
解方程:(x^2+1)(y^2+1)=10 (x+y)(xy-1)=3

解方程:(x^2+1)(y^2+1)=10 (x+y)(xy-1)=3
设X+y=A,Xy-1=B,
第一个方程改变为(x+y)^2+(xy-1)^2=10,这样解就比较方便了,剩下的就比较好解决了

是连等号?还是
:(x^2+1)(y^2+1)=10
(x+y)(xy-1)=3
联立求解呢?

我也不会耶!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
不过你要加油争取自己算出来!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
才是最好的!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!...

这就是一种a=b=c的情况,分开来做,a=c和b=c,题目中c=3,你慢慢做啊。
