实数a,b满足a2-7a+2=0,b2-7b+2=0,则(a+b)2-2ab/ab=
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满足条件a2-7a+2=0,b2-7b+2=0(a≠b),则ba+ab
若实数a,b满足a2+ab-b2=0,则a/b=?
若实数a,b满足条件(a/b)+(b/a)=2,求(a2+ab+b2)/(a2+4ab+b2)的值
已知两实数ab满足条件a2-3ab+2b2=0,求a比b的值
3a2+ab-2b2=0,求a/b-b/a-(a2+b2)/ab (a,b不等于0)
若实数a,b满足a2+ab-b2=0,则ab
已知实数a、b满足等式a2-2a-1=0,b2-2b-1=0,则ba+ab
已知 实数a、b满足方程a2-7a+2=0和b2-7b+2=0,则a/b+b/a=?
已知实数a.b满足下列关系a2-5a+2=0,2b2-5b+1=o求(ab+1)/b的值
先化简,再求值:a/b-b/a-(a2+b2)/ab,其中a2+ab-2b2=0
已知实数a、b满足(a+b)2=1和(a-b)2=25,则a2+b2+ab=______.
