Answer:
Step-by-step explanation:
Recall from the Factor Theorem that if (<em>x</em> - <em>a</em>) is a factor of a polynomial <em>P</em>, then P(<em>a</em>) must equal 0.
Our polynomial is:
And we know that (<em>x</em> - 1) is a factor.
Therefore, by the Factor Theorem, P(1) must equal 0. Hence solve for <em>k: </em>

In conclusion, the value of <em>k</em> is -2.
