Answer:
The value of k that we get is -36.
Step-by-step explanation:
Polynomial means the equation with more than one variables and constants.
For example: x²+x+1 is a polynomial with degree 2.
We are given a quadratic polynomial:
x²-5x+k
A quadratic polynomial is the one with degree 2.
We are also given that one of its root is -4:
So we will put x=-4 in the polynomial given and equate it to 0 as it is a root :
(-4)²-5(-4)+k=0
Solving the equation to get the value of k:
16+20+k=0
k+36=0
k=-36.
Therefore, the value of k in the quadric polynomial x²-5x+k is -4 is -36.
