Negative Square Root Notation
Every positive number has two square roots — one positive and one negative — but the radical sign by convention denotes only the positive (principal) square root. To indicate the negative square root, place a negative sign directly in front of the radical. For example, gives the positive square root, while gives the negative square root. The expression is read as "the opposite of the square root of ." This notation works because the negative sign acts on the already-evaluated radical: first compute the principal square root, then take its opposite.
