Which shows the correct way to divide 2x^3 + 6x^2 – 2x – 5 by x + 3 using synthetic division?

Simplifying
x4 + -2x3 + 6x2 + -2x = 5

Reorder the terms:
-2x + 6x2 + -2x3 + x4 = 5

Solving
-2x + 6x2 + -2x3 + x4 = 5

Solving for variable 'x'.

Reorder the terms:
-5 + -2x + 6x2 + -2x3 + x4 = 5 + -5

Combine like terms:
5 + -5 = 0 -5 + -2x + 6x2 + -2x3 + x4 = 0

The solution to this equation could not be determined
