Question

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

Answer 1

`(x^3+2x^2-3kx-10)/(x+3)`

if a polynomial P(x) is divided by a binomial (x-c) then the remainder is equal to P(c).

where c=-3

`\begin{gathered} P(-3)=-19+9k=8 \\ \text{ }9k=8+19\text{ } \\ 9k=27 \\ k=(27)/(9) \\ k=3 \end{gathered}`

the value of k=3
