Question

The value of k for which (4) is a zero of the polynomial x - x - (2k +2) is
(a) 3
(b) 9
(C) 6 (d)-1​

Answer 1

Answer:

(d) 4-(2k+2) =0

2k +2 = 0

k = -1

Answer 2

Answer

(d)

Step-by-step explanation:

4 is a zero of p(x)

So, substituting the value of x in p(x)

4-4-(2k+2)= 0

-2k-2=0

-2k=2

k=2/-2

k=-1

This is the answer.
