Question

So that X + 1 is factor of the polynomial 2 X square + k then find k

Answer 1

Answer:

k = -2

Step-by-step explanation:

If x +1 is the factor, then

x+1 = 0

x = -1

p(-1) = 2(-1)^2 + k = 0

p(-1) = 2 + k = 0

       = k = -2

Hope it helps

Answer 2

Answer:

x+1 is a factor of 2x^2 + k, by substituting the value of x= -1, then, 2(-1) ^2+k=0, for finding the value of k.

Step-by-step explanation:

=2(-1)^2 + k =0

=2(1)+k=0

=2+k=0

therefore, k = -2, please mark my answer as brainliest
