\[-\sqrt{x}=-1\]
I have to solve for x. And i got 0 but, when i plug it in I dont get -1.
\(\bf -\sqrt{x}=-1\implies -1\cdot \sqrt{x}=-1\implies \sqrt{x}=\cfrac{\cancel{ -1 }}{\cancel{ -1 }}\implies \sqrt{x}=1 \\ \quad \\ (\sqrt{x})^2=(1)^2\implies \sqrt{x^2}=1^2\implies ?\)
First divide both sides by -1 to get \[\Large -\sqrt{x}=-1\] \[\Large \frac{-\sqrt{x}}{-1}=\frac{-1}{-1}\] \[\Large \sqrt{x} = 1\]
What's next?

\[(\sqrt{x})^2 \]and the square root and the ^2 cancel eachother making it X=1
I see what i did wrong. I didnt divide it.
very good, you nailed it
