Question:
for what value of k,[-4]is a zero of the polynomial xsquare-x-[2k- 2]
Answer:
Given, -4 is a zero of the polynomial x2 - x - (2k 2 2)
So, put x = -4 in the polynomial, we get
(-4)2 - (-4) - (2k - 2) = 0
=> 16 + 4 - 2k + 2 = 0
=> 22 - 2k = 0
=> 2k = 22
=> k = 22/2
=> k = 11
So, the value of k is 11
