a.x^2 + 10x^2 + 15x

b.2x + 6

c.x^2 + 2x + 3

d.x^4 + 2x^3 + 3x^2



PART2

Part 1:
(5x^(3) + 10x^(2) + 15x)/(5x) = (5x^(3))/(5x) + (10x^(2))/(5x) + (15x)/(5x) = x^(2) + 2x + 3
The answer is C.

Part 2:
(3x^(4) + 5x^(2) + 2x)/(x) = (3x^(4))/(x) + (5x^(2))/(x) + (2x)/(x) = 3x^(3) + 5x + 2
The answer is A.
