9. In the "Nine Chapters on the Mathematical Art", Qin Jiushao's algorithm is a polynomial simplification algorithm proposed by the mathematician Qin Jiushao during the Southern Song Dynasty in China. In modern times, when using computers to solve polynomial evaluation problems, Qin Jiushao's algorithm remains the optimal algorithm. For example, to calculate the value of the polynomial \(3 x^{3}-4 x^{2}-35 x+8\) when \(x=8\), according to Qin Jiushao's algorithm, the polynomial \(3 x^{3}-4 x^{2}-35 x+8\) can be rewritten as: \(3 x^{3}-4 x^{2}-35 x+8=x\left(3 x^{2}-4 x-35\right)+8=x[x(3 x-4)-35]+8\). 
By calculating in the rewritten form, it involves only 3 multiplications and 3 additions, which saves on the number of multiplications compared to direct calculation, reducing the computational load. The calculation shows that when \(x=8\), the value of the polynomial is 1008. Referring to the above method, the polynomial \(x^{3}+2 x^{2}+x-1\) can be rewritten as \(\qquad\), and when \(x=8\), the value of the polynomial is \(\qquad\).
Answer: $x[x(x+2)+1]-1,647$
