\sqrt{x}=-x
Subtract x from both sides of the equation.
\left(\sqrt{x}\right)^{2}=\left(-x\right)^{2}
Square both sides of the equation.
x=\left(-x\right)^{2}
Calculate \sqrt{x} to the power of 2 and get x.
x=\left(-1\right)^{2}x^{2}
Expand \left(-x\right)^{2}.
x=1x^{2}
Calculate -1 to the power of 2 and get 1.
x=x^{2}
Reorder the terms.
x-x^{2}=0
Subtract x^{2} from both sides.
x\left(1-x\right)=0
Factor out x.
x=0 x=1
To find equation solutions, solve x=0 and 1-x=0.
0+\sqrt{0}=0
Substitute 0 for x in the equation x+\sqrt{x}=0.
0=0
Simplify. The value x=0 satisfies the equation.
1+\sqrt{1}=0
Substitute 1 for x in the equation x+\sqrt{x}=0.
2=0
Simplify. The value x=1 does not satisfy the equation.
x=0
Equation \sqrt{x}=-x has a unique solution.
