Here’s a quick one for anyone brushing up on algebra and number properties:
Step 1: F(2) = 23(8) + 3 = 184 + 3 = 187
Step 2: Prime factors → 11 and 17
Step 3: Average = (11 + 17) / 2 = 14
✅ Answer: B (14)
Always check factorization carefully — numbers like 187 can look tricky at first glance!
F(x) = 23x³ + 3
If x = 2, what is the average of the prime factors of F(x)?
A) 12 B) 14 C) 16 D) 11 E) 17
Step 1: F(2) = 23(8) + 3 = 184 + 3 = 187
Step 2: Prime factors → 11 and 17
Step 3: Average = (11 + 17) / 2 = 14
✅ Answer: B (14)
