Answer» Factortheorem:
If p(x) is a polynomial of degree n≥ 1 and "a" is any real NUMBER, then (x-a) is a factor of p(x) , if p(a) = 0. ________________________ Let \:p(x) = x^{3} - 6x^{2} + 11x - 6Letp(x)=x 3 −6x 2 +11x−6 \begin{GATHERED}i )Let \: x = 1\\ \IMPLIES p(1) = 1^{3}-6\times 1^{2}+11\times 1 -6 \\= 1 - 6 + 11 - 6 \\= 12 - 12 \\= 0\end{gathered} i)Letx=1 ⟹p(1)=1 3 −6×1 2 +11×1−6 =1−6+11−6 =12−12 =0
