Answer 3

To simplify the expression (2 - √3)^2, we need to expand it and perform the necessary calculations. The square of a binomial expression can be expanded using the formula:

(a - b)^2 = a^2 - 2ab + b^2

In this case, a = 2 and b = √3. Let's apply the formula:

(2 - √3)^2 = 2^2 - 2 * 2 * √3 + (√3)^2 = 4 - 4√3 + 3 = 7 - 4√3

So, the simplified expression is 7 - 4√3.
