Given:
One of the two roots of the given equation is double the additive inverse of the other.
To find:
The value of k.
Solution:
Let two roots of the given equation are 
and 
.
According to the question,
(Additive inverse of is 
)
If and are roots of the quadratic equation 
then
We have,
Here, a =1, b=k and c=-98.
![[\because \beta=-2\alpha]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cbeta%3D-2%5Calpha%5D)
...(i)
Now,
Divide both sides by -2.
Taking square root on both sides.
Using (i), we get
Therefore, the value of k is either -1 or 1.
