Answer:
[tex]x=\sqrt{10}[/tex]
Step-by-step explanation:
The given equation is :
[tex]5-2x^2=-15[/tex]
We need to solve it using inverse operations.
Subtract 5 from both sides of the equation.
[tex]5-2x^2-5=-15-5\\\\-2x^2=-20\\\\2x^2=20\\\\x^2=10\\\\x=\sqrt{10}[/tex]
So, the solution of the given equation is [tex]x=\sqrt{10}[/tex].
