2(a²b+ab²)-2(a²b-1)-2(a²b-1)-2ab²-2其中a=-2,b=2
2(a²b+ab²)-2(a²b-1)-2(a²b-1)-2ab²-2其中a=-2,b=2

2(a²b+ab²)-2(a²b-1)-2(a²b-1)-2ab²-2其中a=-2,b=2
2(a²b+ab²)-2(a²b-1)-2(a²b-1)-2ab²-2
=2a²b+2ab²-2a²b+2-2a²b+2-2ab²-2
=-2a²b+2
=-2*4*2+2
=-14

2(a²b+ab²)-2(a²b-1)-2(a²b-1)-2ab²-2
=2a²b+2ab²-2a²b+2-2a²b+2-2ab²-2
=-2a²b+2
=-2*(-2)²*2+2
=-16+2
=-14

题目错了吧
