Aleks [24]

Answer:

The third option (9+3\sqrt{7}-3\sqrt{7}-\sqrt{49})

Step-by-step explanation:

With FOIL, this can be expanded. (a+b)(a-b) is equal to a²+ab-ab-b² or a²-b².

In this case, all the answers have 4 terms, so we want the first option. This makes the equation 3²+(3×\sqrt{7})-(3×\sqrt{7})-(\sqrt{7})².

Solving these gives 9+3\sqrt{7}-3\sqrt{7}-7. This is the same as  9+3\sqrt{7}-3\sqrt{7}-\sqrt{49}.

**This content involves multiplying with surds and expanding perfect squares, which you may wish to revise. I'm always happy to help!
