Question 225127: I need help with this problem:

You can put this solution on YOUR website!
Move the 3 to the other side:
x%5E2+-+2x-8+%3E0
Then we can factor:
%28x-4%29%28x%2B2%29%3E0
To finish solving, set both of these as follows:
%28x-4%29%3E0, %28x%2B2%29%3E0
Solve for x by moving the numbers to the other side:
x%3E4, x%3E-2
Those are your answers.
