see this .. friends ...

Answer 2

Explanation :

Yes. Except for zero, every number has two square roots, one positive and one negative. The primary square root, abbreviated as b, is the positive square root. Write b to indicate the negative root, and b to indicate both roots.

Because a positive number multiplied by itself is positive, and a negative number multiplied by itself is also positive, a positive number has two square roots.

For example, we assume $N$  is number , It's have $-\sqrt{N}$ and $+\sqrt{N}$
