Question

Simplest form w^3-w(w^2+2w-1)+2w

Answer 1

`- 2 {w}^(2) + 3w`

Solution,

`{w}^(3) - w( {w}^(2) + 2w - 1) + 2w \\ = {w}^(3) - {w}^(3) - 2 {w}^(2) + w + 2w \\ = - 2 {w}^(2) + 3w`

Some rules:

`( + ) * ( + ) \ = ( + ) \\ ( - ) * ( + ) = ( - ) \\ ( + ) * ( - ) = ( - ) \\ ( - ) * ( - ) = ( + )`

Hope this helps...

Good luck on your assignment..
