Answer 1

Answer:

Answer:

k=-5

Step-by-step explanation:

Given----->

if (x-1) is factor of x²+9x-5+k

to find value of K

\begin{gathered} {x}^{2} + 9x - 5 + k = 0 \\ \\ {1}^{2} + 9 \times 1 - 5 + k = 0 \\ \\ 1 + 9 - 5 + k = 0 \\ \\ 5 + k = 0 \\ \\ k = - 5\end{gathered}x2+9x−5+k=012+9×1−5+k=01+9−5+k=05+k=0k=−5
