Question

Urgent! Pls Answer it
If a=2, b=-2 find the value 2a²b+2ab²+ab

Answer 1

Hope you understand it!

Answer 2

Given that:

`a=2, b=-2`

Substituting these values,

`2a^(2) b+2ab^(2) +ab`

`= > 2 * ({2} * 2) * ( - 2) + 2 * 2 * ( - 2 * - 2) + (2 * - 2)`

`= > 2 * 4 * ( - 2) + 4 * 4 + ( - 4)`

`= > 8 * ( - 2) + 16 + ( - 4)`

`= > - 16 + 16 + (- 4)`

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

`- 4`
