## 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).

### What is the value of under root X square?

⇒√x2=±x . Hence, the square root of x squared is ±x. Note: We can verify whether x is the square root of √x2 . We know that Square root of a number is a value which when multiplied by itself gives the original number.

**Why is the square root of (X square) equal to a IXI?**

Originally Answered: Why is the square root of (x square) equals to a IxI (absolute value) while the (root of x) square equals x? Depends on the type of numbers being allowed. With no restrictions there are ALWAYS TWO square roots of any number.
