Introduction:
In this problem, we are given a quadratic polynomial and we need to find the value of k such that the sum of its zeroes is equal to half of their product.
Quadratic Polynomial:
The given quadratic polynomial is x^2 - (k 6)x + 2k - 1
Sum and Product of Roots:
Let the roots of the quadratic polynomial be α and β.
Then, we know that:
α + β = -(coefficient of x)/coefficient of x^2 = (k 6)
αβ = constant term/coefficient of x^2 = 2k - 1
Equation:
We need to find the value of k such that the sum of the roots is equal to half of their product.
i.e., (α + β) = (1/2)αβ
Substituting the values of α + β and αβ, we get:
(k 6) = (1/2)(2k - 1)
2(k 6) = 2k - 1
2k - 12k + 6 = 0
k = 3
Conclusion:
Hence, the value of k such that the sum of the roots of the quadratic polynomial x^2 - (k 6)x + 2k - 1 is equal to half of their product is k = 3.
