+) \(f\left(x\right)=a_nx^n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}+...+a_1x+a_0\)
+) \(f\left(x\right)=p\left(x\right)\left(x-\alpha\right)\)
lược đồ:
\(\alpha\) | \(a_n\) | \(a_{n-1}\) | \(a_{n-2}\) | ... | \(a_1\) | \(a_0\) |
\(\alpha\) | \(b_n=a_n\) | \(b_{n-1}=\alpha b_n+a_{n-1}\) | \(b_{n-2}=\alpha b_{b-1}+a_{n-2}\) | ... | \(b_1=\alpha b_2+a_1\) | \(r=\alpha b_1+a_0\) |
rồi giải đi :v
