若实数a,b满足a2+ab+b2=0,则a/b=
若实数a,b满足a2+ab-b2=0,则a/b=?
若实数a,b满足a2+ab-b2=0,则ab
若实数a,b满足a2+a-1=0,b2+b-1=0,则ab+ba
已知实数a,b满足方程(a2+b2+5)(a2+b2-5)=0,则a2+b2=______
若实数a,b满足条件(a/b)+(b/a)=2,求(a2+ab+b2)/(a2+4ab+b2)的值
实数a,b 满足a2+b2=1 则ab范围
若非零实数a、b满足4a2+b2=4ab,则ba等于( )
实数a,b满足a2-7a+2=0,b2-7b+2=0,则(a+b)2-2ab/ab=
已知实数a、b满足a2+b2+a2b2=4ab-1,则a+b的值为______.
已知实数a,b满足条件a2-7a+2=0,b2-7b+2=0(a≠b),则ba+ab
a、b为实数,且满足a>b>0,a2+b2=4ab,则a-ba+b的值等于 ___ .
若实数a,b满足a2=2a+1,b2=2b+1,则a+b=?
