Answer:
[tex]x=-\sqrt{10}[/tex] or [tex]x=\sqrt{10}[/tex]
Step-by-step explanation:
The given equation is
[tex]x^2=10[/tex]
We use the square root method to solve this quadratic equation;
We take square root to obtain;
[tex]x=\pm \sqrt{10}[/tex]
Split the plus or minus sign to obtain;
[tex]x=-\sqrt{10}[/tex] or [tex]x=+\sqrt{10}[/tex]
