Answer:
the solution set is {0,-11}
Step-by-step explanation:
The equation is [tex]-p^2-11p=0[/tex]
The GCF of the left hand side of the expression is -p. Hence, factored out the GCF
[tex]-p(p+11)=0[/tex]
Now, apply the zero product property, we get
[tex]-p=0,p+11=0[/tex]
Now, solve the equations for p
[tex]p=0,p=-11[/tex]
Thus, the solution set is {0,-11}
