Would someone mind verifying this for me?
there are two critical values ... , where the expression is undefined, and , where the expression equals 0.
these two "critical" values break up the values for x into three sections ...
pick any value for x in each section and test it in the original inequality to see if it makes the inequality true ... if the inequality is true for that value of x, then all values of x in that interval will make the inequality true.
if false, then all values of x in that interval make the inequality false.
