To complete the vector equation QA + __ = QB, we need to find the vector that, when added to QA, results in QB. Let's break it down step by step:

1. Start by examining the given equation QA + __ = QB, where QA and QB are vectors.
2. Since we want to find the missing vector, let's refer to it as __.
3. To find the missing vector, we can subtract QA from both sides of the equation:

(QA + __) - QA = QB - QA

4. By subtracting QA from both sides, we cancel out QA on the left-hand side, leaving:

__ = QB - QA

5. The resulting vector, QB - QA, is obtained by subtracting the individual components of QA from the corresponding components of QB. For example, if QA = ⟨a, b, c⟩ and QB = ⟨x, y, z⟩, then the missing vector __ would be:

__ = ⟨x - a, y - b, z - c⟩

This completes the vector equation QA + __ = QB, where __ is equal to QB - QA.
