x – a is the factor of a polynomial P(x) if P(a) is equal toQuestion 9 options:A) 2B) 0C) 1D) 3

Answer 1

If (x-a) is a factor of a polynomial then when x=a the function is equal to:

$\begin{gathered} f(x)=(x-a)\cdot\ldots \\ \\ f(a)=(a-a)\cdot\ldots \\ \\ f(a)=0\cdot\ldots \\ \\ \text{ If one of the factors is equal to zero the function is equal to zero} \end{gathered}$Then, (x – a) is the factor of a polynomial P(x) if P(a) is equal to: 0
