Don’t know why you are being down voted. You are correct. There is a difference between a square root and the solutions of x2 = n.

Yeah, square root implies absolute numbers. You need to manually multiply by -1 to get the other solution to x^2

No?

In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For example, 4 and −4 are square roots of 16 because 4² = ( − 4 )² = 16.

Wikipedia

Edit: I’m wrong lol, there is a difference between the square root function, which accepts two results, and the square root, or principal square root, which is a unique positive number

Superposition isn’t the same thing as a simultaneous existence. There are not two cats in the box.

Comic Strips is a community for those who love comic stories.

The rules are simple:

  • The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author’s website, for instance).
  • The comic must be a complete story.
  • If it is an external link, it must be to a specific story, not to the root of the site.
  • You may post comics from others or your own.
  • If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
  • The comic can be in any language, but if it’s not in English, OP must include an English translation in the post’s ‘body’ field (note: you don’t need to select a specific language when posting a comic).
  • Politeness.
