What is the set of all solutions to the equation square root x 2 =- X?

What is the set of all solutions to the equation sqrt(x+2)=-x? There are no solutions to the given equation.

Why does sqrt x 2 )=| x?

so since x is positive then √x is positive, then (√x)^2 is positive. But in √x^2=|x| the “x^2” inside is for sure positive, then “x” can be either positive or negative, that’s why when you do the square root of x^2, it’s an absolute value. The square root of x^2 could either be a positive or a negative number.

Is sqrt x 2 the same as X?

thanks to all. sqrt(x^2) equals x if x>0 and -x otherwise. |x| equals x if x>0 and -x otherwise. Therefore, sqrt(x^2) = |x|.

What is the set of all solution to the equation?

solution set
The set containing all the solutions of an equation is called the solution set for that equation. If an equation has no solutions, we write ∅ for the solution set. ∅ means the null set (or empty set).
