Question

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


`5 - 2x^2 = - 15`

Answer 1

`x=√(10)`

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=√(10)`

So, the solution of the given equation is
`x=√(10)`.
