Answer: It's C f"(x)= 15x^2+235 Hope that helps!
Step-by-step explanation:
Find the Greatest Common Factor (GCF).
GCF = 5
2. Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
5(15x^2/5+235/5)
3. Simplify each term in parentheses and that would give you 5(3x^2+47) and that's why I think it C but i'm not so sure but if you get it right can you please make me Brainliest bye and I hope you get it right!
