Resposta: x³ - x² + 8x + 10

Explicação passo-a-passo:

(x^2 - 2x + 10) . (x+1)\\

[(x^2).(x+1)] -[(2x).(x+1)]+[(10).(x+1)]

Realiza-se primeiro as operações que estão dentro dos colchetes

[x^3 + x^2] - [2x^2 + 2x]+[10x + 10]\\x^3 + x^2 - 2x^2 - 2x + 10x+ 10\\x^3 - x^2 + 8x + 10

Espero ter ajudado :)
