You can put this solution on YOUR website!
x%5E2-25%3C=0

%28x-5%29%28x%2B5%29%3C=0

You can try examining around the critical values, or you can use simple knowledge of roots of a quadratic equation, how that relates to a parabola.

Critical x values at -5 and 5.
Where the quadratic less than or equal 0? BETWEEN them, INCLUSIVE.
If you have trouble with this, say so; otherwise,...

SOLUTION: highlight%28-5%3C=x%3C=5%29


(Choice F is near, but not sufficient).
