Answer 1

`\qquad \qquad\huge \underline{\boxed{\sf Answer}}`

Let's solve ~

`\qquad \sf  \dashrightarrow \: (x {}^(3) - 4x {}^(2) + 1) + (3 {x}^(2) + x)`

`\qquad \sf  \dashrightarrow \: {x}^(3) - 4 {x}^(2) + 1 + 3 {x}^(2) + x`

`\qquad \sf  \dashrightarrow \: {x}^(3) - 4 {x}^(2) + 3x {}^(2) + x + 1`

`\qquad \sf  \dashrightarrow \: {x}^(3) - {x}^(2) + x + 1`
