Question

Expand and simplify difference of squares

Answer 1

\[\huge (\sqrt{x}-\sqrt{2})(\sqrt{x}+\sqrt{2})\]

Answer 2

Identity: (a+b)(a-b)=a^2-b^2 ..
You can evaluate this by solving the two brackets.

Answer 3

when you multiply two same radicals, the radicals are undone so you should have x and 2, and since your factor contains - and +, you wouldn't have a middle term

Answer 4

would the answer just be (x-2) ?

Answer 5

Yes
