I'm looking answer for my question please answer for me number one work out find value of k

if a polynomial P(x) is divided by a binomial (x-c) then the remainder is equal to P(c).
where c=-3
[tex]\begin{gathered} P(-3)=-19+9k=8 \\ \text{ }9k=8+19\text{ } \\ 9k=27 \\ k=\frac{27}{9} \\ k=3 \end{gathered}[/tex]the value of k=3
