if x+2 is a factor of the given polynomial then x+2=0 or x = -2 must satisfy the equation by giving the result 0
Therefore
2(-2)³+5(-2)² - (-2) - k = 0
-16+20+4-k = 0
k = 8
incorrect answer
oops my bad
theres a minor calculation mistake if you can see through the solution
i have written -(-2) as +4 ..anyway thats wrong on my part .my apologies
