Mathematics for IGCSE & O level - Algebraic Manipulation (Section 4 - No. 38)

What is the correct way to expand a bracket with a negative number?
-2(x + 3) = -2x + 6
-2(x + 3) = -2x - 6
-2(x + 3) = 2x - 6
-2(x + 3) = 2x + 6

توضیح

You must distribute the negative sign to each term inside the bracket.
