Square root is not defined to for negative values. For negative values, the answer of square root is a complex number which is not in Real Domain.
So any such values, for which the expression is not defined are not in the Domian. So the domian of square root of x will be All real numbers greater than or equal to 0.
This can be expressed as:
[0 , ∞)
or
x ≥ 0
Answer: who ever arrives at the answer x=0/3 =0 is correct
Step-by-step explanation:
Even though I need supporting details from the individual answers of Jane and Jill to pass my own judgment.
Given the expression
(2x²+x) +2(-x²+×)=0
Let's us open the bracket
2x²+x-2x²+2x=0
Collecting like terms
2x²-2x²+x+2x=0
3x=0
x=0/3
x=0
