若a+b=3,ab=2,则a^2b+ab^2=()若a+b=3,ab=2,则a^2b+ab^2=()若a+b=3,ab=2,则a^2b+ab^2=()6解;a^2b+ab^2=ab(a+b)=2*3=
若a+b=3,ab=2,则a^2b+ab^2=( )
若a+b=3,ab=2,则a^2b+ab^2=( )
若a+b=3,ab=2,则a^2b+ab^2=( )
6
解;
a^2b+ab^2=ab(a+b)=2*3=6
若a-b=3ab,则2a-ab-2b/a+2ab-b=?
若a+b-ab=0,则(3a+3b-ab)/(2a+2b+ab)=
若ab^2=-6,则-ab(a^2b^5-ab^3-b)=?
若a/b=2 则a*a-ab+b*b/a*a+b*b等于?
ab/a+b=3 a-2ab+b/2a-3ab+2b?
若a+b=3 ab=-2,求a+ab+ab+b的值
a^2-3ab+b^2/ab=( )/ab-3
a^2-3ab+b^2/ab=( )/ab -3
1/a+1/b=3则a-ab+b/a+2ab+b值是?
若a+b=3,ab=2,则a^2b+ab^2=( )
A-B=-1,AB=-2,则(2A-3B-AB)-(A-2B+3AB)=?”
已知a+b/2ab=3,则3a-7ab+3b/a+3ab+b=?
若a-b=3ab,求2a-ab-2b除以a+2ab-b的值
若a+b=3,ab=-2,求(5a-5b-ab)-(4a-6b-3ab)
a-b=3ab,则代数式2a-2b-ab/a-b+2ab的值是()
a-b=3ab,则代数式2a-2b-ab/a-b+2ab的值是()
如a-b=4,ab=1,则(2-ab+2a+5b)-(3ab+2b-2a)-(3a+4b-ab)=
若a-b=4,ab=1,求(-2ab+2a+3b)-(3ab+2b-2a)-(a+4b+ab)的值
