What is the value of 'k' in polynomial x^2 8x k, if -1 is a zero of ...
Introduction
To find the value of 'k' in a polynomial, given that -1 is a zero of the polynomial.
Explanation
-1 is a zero of the polynomial, which means that when x = -1, the value of the polynomial is zero. So, we can substitute x = -1 in the given polynomial and solve for 'k'.
Solution
The given polynomial is x^2 + 8x + k. When x = -1, the polynomial becomes:
(-1)^2 + 8(-1) + k = 0
1 - 8 + k = 0
k = 7
So, the value of 'k' in the polynomial x^2 + 8x + k, if -1 is a zero of the polynomial is 7.
Conclusion
The value of 'k' in a polynomial can be found by substituting the zero of the polynomial in the given polynomial and solving for 'k'. In this case, the value of 'k' is 7 when -1 is a zero of the polynomial.
