Question

- (x^2 - 3x + 2) - x(x - 4)

Answer 1

`= - 2 {x}^(2) + 7x - 2`

Explanation:

`- ( {x}^(2) - 3x + 2) - x(x - 4)`

`- {x}^(2) + 3x - 2 - x(x - 4)`

`- {x}^(2) + 3x - 2 - {x}^(2) + 4x`

`- {2x}^(2) + 3x - 2 + 4x`

`\boxed{\green{ = - 2 {x}^(2) + 7x - 2}}`

Answer 2

`- (x^(2) - 3x + 2) - x(x - 4) \\ = ( - x^(2) + 3x - 2) + ( - x ^(2) + 4x) \\ = - 2 {x}^(2) + 7x - 2`
