Why does the square root of 16 have two answers?

There are always two solutions to the square root of a number: a positive response and a negative answer. Because the square of a negative and positive integer is the same, there are two possible solutions.

Squares are the numbers that are produced when a value is multiplied by itself. In contrast, a number's square root is a value that, when multiplied by itself, returns the original value.

The values that result from multiplying an integer by itself are known as square numbers. Among the attributes are:

The square of one is one.
Positive squares have positive characteristics.
The square of a negative integer has a positive aspect as well.
Square of 0 equals 0
The value under the root is equal to a number's square root.
Only even numbers will be present in every even number's unit location of square.
A number's square ends in 1 if either 1 or 9 were substituted for the unit.
If a number has a 4 or 6 in the place of the unit, then the square it forms ends in 6.
