Answer:
C. 
Step-by-step explanation:
The polynomial form that reveals most quickly the zeroes is the form of a product of binomials. That is:

Where
is the product function and
is the i-th root of the polynomial.
Hence,
resembles a form that is close to the form described above. The right option is C.
Answer:
(g ○ f)(- 5) = 4
Step-by-step explanation:
evaluate f(- 5) then substitute the value obtained into g(x)
f(- 5) = (- 5)² + 6(- 5) + 3 = 25 - 30 + 3 = - 2 , then
g(- 2) = 2(- 2) + 8 = - 4 + 8 = 4
(g ○ f)(- 5) = 4
