A. 2x^2 + 8x + 3
B. 2x^2 - 8x - 3
C. 2x^2 - 8x + 3
D. 2x^2 + 8x - 3

I really need help with this if anybody has any idea I would really appreciate it!
A = L * W,
A = L*(x + 4) = 2x^3 - 29x + 12,
L = (2x^3 - 29x + 12)/(x+4),
Use long-hand division,
L = 2x^2 - 8x + 3.
A = L*(x + 4) = 2x^3 - 29x + 12,
L = (2x^3 - 29x + 12)/(x+4),
Use long-hand division,
L = 2x^2 - 8x + 3.
