Question

if x= -½ is a zero of the polynomial p(x) = 8x³-k , then find the value of k.​

Answer 1

Answer:

k = (-1)

Step-by-step explanation:

p(x) = 8x³-k

=> p(-1/2) = 8 (-1/2)^3 - k

=> 0 = 8 (-1/8) - k ( Given x= -½ is a zero of the polynomial p(x) = 8x³-k. So, p(-1/2) = 0 )

=> k = (-1) answer.
