Question

If (x+1) is a factor of the polynomial 2x^2+know, then the value of k is

Answer 1

Answer:

Here is your answer, mate:- k = -4

Step-by-step explanation:

p(x) = 2x² + 2 + k

=> x + 1 = 0

∴ x = -1

p(-1) = 0

p(-1) = 2 × (-1)² + 2 + k = 0

p(-1) = 2 × 1 + 2 + k = 0

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

p(-1) = 4 + k = 0

=> 4 + k = 0

=> k = -4

∴ The value of k is -4
