Question

Find the value of , ( − 1) is the factor of
2 + 9 − 5 + ​

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}

x 2

+9x−5+k=0

1 2

+9×1−5+k=0

1+9−5+k=0

5+k=0

k=−5
