no, the square root of a number is always the positive

i.e. if x is the square root of 4, then x is 2.

however, if you state that x squared is 4, then x can be both +/- 2.

so you have to be careful!

my teacher marked me off on a test because of that once

But you always forget, and end up with only half the answer to your equation

Exactly, it's only when you are trying to solve an equation. If it's just simply: What is the square rooot of 4, then the answer is 2. If it's: X^2=4, then the answer is X = +/-2.

The square root of a number only represents the positive number. x^2=4 has 2 answers: +/-2. But the square root of 4 is only 2.

It's not summer everywhere, idiot. And some people enjoy maths.

Also, I think you might have bumped your caps lock key.

square root of any positive number has two answers, like square root of 4 is 2 and -2, as -2X-2=4 and 2X2=4

for negative integers you have to use imaginary numbers, the square root of -4 is 2i and -2i. but you only need to start worrying about square rooting negative numbers if you are continuing maths to a higher level than just year 11 and GCSE's
