The roots of the quadratic function $f(x) = -x^{2}-6\cdot x -8$ are $x_{1} = -4$ and $x_{2} = -2$ .

Step-by-step explanation:

Let be $f(x) = -x^{2}-6\cdot x -8$ , the function is now graphed by using a graphing tool and whose outcome is added below as attachment. After looking the image, the roots of the polynomial are $x_{1} = -4$ and $x_{2} = -2$ , respectively. It can be also proved by algebraic means:

1) $-x^{2}-6\cdot x -8=0$ Given
