Solve for x This must be solved by the first method in the textbook (the method of Example 1.1 method of Example 1.18): the second method will not work. [You can do the translation, but the resulting quadratic inequalit method anyway, so you might as well start there] ties cannot be solved except by resorting to the first In the student solution box, post your COMPLETE solution, showing ALL work, and please use nice math notation as indicated in this post: 6 Note: if you find an error in the student solution once someone has posted one, or you want to do not use a followup for this!

|x2-5x|6
=>(x2-5x)-6,(x2-5x)6
=>x2-5x+60,x2-5x-60
=>(x-2)(x-3)0,(x+1)(x-6)0
=>2x3 ,x-1 ,x6
so the solution set is S= (-,-1]U[2,3]U[6,)
