Answer 2

Answer:

1

Step-by-step explanation:

One of the most useful identities is the factorization of a difference of squares: $a^2 - b^2=(a+b)(a-b)$

. (Just multiply it out. FOIL works fine: the outer and inner terms cancel.)

The given problem is the factorization of the difference of squares $a^2-b^2$

with a=2 and b=$\sqrt{3\\}$. Since $a^2$=4 and b2=3, we get (2+

.

The given expression is equal to 1.
