The value of k is 12.
Step-by-step explanation:
If a polynomial is , then
Sum of zeros = -b/a
Product of zeros = c/a
The given polynomial is
It is given that α and β are zeros of the given polynomial.
Here, a=1, b=-7 and c=k.
... (1)
... (2)
It is given that
... (3)
On adding (1) and (3) we get
Substitute in equation (1).
Substitute and in equation (2).
Therefore, the value of k is 12.
