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)
So, put x = -4 in the polynomial, we get
(-4)2 - (-4) - (2k + 2) = 0
=> 16 + 4 - 2k - 2 = 0
=> 20 - 2k - 2 = 0
=> 18 - 2k = 0
=> 2k = 18
=> k = 18/2
=> k = 9
So, the value of k is 9
