ANSWER

Or

EXPLANATION
The given polynomial is

where a=1,b=k, c=30
Let the zeroes of this polynomial be m and n.
Then the sum of roots is

and the product of roots is

The square difference of the zeroes is given by the expression.

From the question, this difference is 169.
This implies that:





We substitute the values of k into the equation and solve for x.


The zeroes are given by;
