Answer:
The answer to your question is x= −3 or it can be x=3
Steps of solving
The first step we have to do to solve this equation is to Factor left side of our equation
(x+3)(x−3)(x^2+10)=0
The second step that we would have to do would be Setting the factors that equal to 0.
You can go with any of these
x+3=0, x−3=0 or you can lastly go with x^2+10=0
And that's how you would get your answer : x= −3 or x=3
