Answer:
Answer: The values of k are -4 and 4
Step-by-step explanation:
The given polynomial is (k²-14)x²-2x-12
The sum of zeros of a quadratic equation is -b/a.
Hence, the sum of the zeros of the given quadratic is
-(-2)/(k²-14)
2/(k²-14)
Now, from the given directions, this expression should be equal to 1.
2/(k²-14) = 1
k²-14 = 2
k² = 16
k = ñ4
