Question

If X + 1 is a factor of the polynomial 2 X square
+ kx then find the value of k

Answer 1

Answer:

-2

Step-by-step explanation:

x + 1 = 0

x = -1

p ( x ) = 2x² + kx

p ( -1 ) = 2 ( -1 ) + k ( -1 )

0 = -2 - k

k = -2

Answer 2

▪♥️HELLO MATE♥️▪

here is your answer...

⤵️⤵️⤵️

x + 1 = 0

x = (-1)

then,

p(x) = 2x² + kx

p(-1) = 2(-1)² + k(-1)

= 2(1) + (-1k)

= 2 - 1k

Now,

2 - 1k = 0

(-1k) = -2

k = -2 + 1

k = -1

Hence, the value of K is (-1)
