Given that:

a=2, b=-2

Substituting these values,

2a^{2} b+2ab^{2} +ab

=  > 2 \times ({2} \times 2) \times ( - 2) + 2 \times 2 \times ( - 2 \times  - 2) + (2 \times  - 2)

=  > 2 \times 4 \times ( - 2) + 4 \times 4 + ( - 4)

=  > 8 \times ( - 2) + 16 + ( - 4)

=  >  - 16 + 16 +  (- 4)

As first two 16's will be cancelled as they have opposite signs, so, the remaining is,

- 4
