Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.

REY [17]

Answer:

$x=\sqrt{10}$

Step-by-step explanation:

The given equation is :

$5-2x^2=-15$

We need to solve it using inverse operations.

Subtract 5 from both sides of the equation.

$5-2x^2-5=-15-5\\\\-2x^2=-20\\\\2x^2=20\\\\x^2=10\\\\x=\sqrt{10}$

So, the solution of the given equation is $x=\sqrt{10}$ .
