Question

I remember my teacher saying something about you square root an answer like 121 the answer is -11 and +11

But, this also is not true for all the answers

Could someone tell me when I square root a number, when it is both a + and -, and when it is just a + .

Answer 1

The square root of any number can be either positive or negative.

When you multiply two negative numbers together, the answer is positive.

Answer 2

Yes
