Question

{-4,4} write in set builder form​

Answer 1

Answer:

{x|x∈Z,x=$\sqrt{16}$} where, Z= Integer

Mark me the brainiest

Answer 2

Answer:

Well this question can have multiple answers, but here is the best one according to me

(x+4)(x-4)=$x^{2}$-16

so, as you can see the roots of this equation are 4 and -4

∴ we can say that {-4,4} in set builder form is:-

{x:x is a root of the equation, $x^{2}$-16}

You can also include x∈Z but that is optional since this can only have 2 possible roots.

I hope this helps..!

KUDOS!!
