Answer:


x=-15,x=-1

Step-by-step explanation:

We are given:


x^2+16x+15

We will find the zeros of the polynomial as shown below:


\begin{gathered} x^2+16x+15=0 \\ \text{Factorise, we have:} \\ x^2+15x+x+15=0 \\ x(x+15)+1(x+15)=0 \\ x+15=0,x+1=0 \\ x=-15,x=-1 \\ \\ \therefore x=-15,x=-1 \end{gathered}

Therefore, the correct option is: -1 and -15
