Question

if x + 1 is a factor of the polynomial 2x²+kx,then the value of k is​

Answer 1

Answer:

value of k is ​2.

Step-by-step explanation:

Consider p(x) = 2x² + kx

As x + 1 is a factor of p(x)

p(-1) = 0

Substituting x = - 1

2(-1)² + k(-1) = 0

By further calculation

2 - k = 0

k = 2

Therefore, the value of k is 2.

Hence, the answer is 2.
