To simplify the expression [tex]\(-\sqrt{4}\)[/tex]:
1. First, determine the square root of 4. The square root of 4 is a number which, when multiplied by itself, equals 4. In this case, [tex]\(\sqrt{4} = 2\)[/tex].
2. Next, apply the negation to the result of the square root. Negating the number 2 gives [tex]\(-2\)[/tex].
Thus, the simplified expression [tex]\(-\sqrt{4}\)[/tex] is:
[tex]\[
-\sqrt{4} = -2
\][/tex]
Therefore, the final answer in the box is:
[tex]\[
\boxed{-2}
\][/tex]
