Because the power of x is an even number, there will be a positive (>0) and negative (<0) solution for x.
the solutions are x=2 or x=-2
you can check this by plotting the graph and the solutions are where the curve touches the x-axis:

I hope this helps.
P.S. I am trying to start my own mathematics homework help website. I would be extremely grateful if you would send me your feedback on my help to adam.chapman@student.manchester.ac.uk.
