      Đáp án:

      Ta có

      ` x^3  -9x^2 + 6x + 16 \vdots x +1`

      ` => f(-1) = 0`

      ` => (-1)^3 – 9.(-1)^2 + 6.(-1) + 16 = 0`

      ` => -1 – 9 – 6 + 16 = 0`

      ` => 0 = 0` ( đúng ) 

      ` => f(x) \vdots x +1`

      Đáp án:

       

      Giải thích các bước giải:

      `f(x)=x^3-9x^2+6x+16`

      `=x^3+x^2-10x^2-10x+16x+16`

      `=x^2(x+1)-10x(x+1)+16(x+1)`

      `=(x+1)(x^2-10x+16)`

      Vì `(x+1)\vdotsx+1`

      `=>(x+1)(x^2-10x+16)\vdotsx+1`

      `=>f(x)=x^3-9x^2+6x+16\vdotsx+1(dpcm)`
