Pl help! i will give brainliest 100 points! Let f(x) = 8x3 + 16x2 − 15 and g(x) = 2x + 1. Find f of x over g of x. A. 4 times x squared plus 6 times x minus 3 plus 12 over the quantity 2 times x plus 1 B. 4 times x squared plus 6 times x plus 3 plus 12 over the quantity 2 times x plus 1 C. 4 times x squared plus 6 times x minus 3 minus 12 over the quantity 2 times x plus 1 D. 4 times x squared plus 6 times x plus 3 minus 12 over the quantity 2 times x plus 1

C. 4 times x squared plus 6 times x minus 3 minus 12 over the quantity 2 times x plus 1

Step-by-step explanation:

f(x) = 8x^3 + 16x^2 − 15

g(x) = 2x + 1.

f(x) / g(x) = (8x^3 + 16x^2 − 15) / (2x + 1)
