Quadratic Inequality Algebra Equations

08/10/15

Hi . Good Evening. I would just like to ask if there's a possibility that quadratic inequality has extraneous solution or roots? Thank you very much.
I got this question very confusing when I competed for Math Olympiad this year in Chicago, USA. By the way, I'm from Philippines. I hope you can answer my question immediately. Thanks.
