The way to find the factores is by seeking the polonomial's roots, or zeros!
To find the roots, we set the polinomial equation to zero:
x^2+16y^2=0
Then we solve this equation:
x^2=-16y^2
This is only true, if x=y=0.

Answer:
S = 2π(4)^2 + 2π(4)(16)
Step-by-step explanation:
The surface area of a cylinder can be found using this equation: 2(πr^2) + 2(πrh). Therefore the answer would be the first one: S = 2π(4)^2 + 2π(4)(16)
