Solve the inequality //(2x1)(x+3)/4/< 1
where /x/ is the modulus of x.

why not just use , since / is usually used for division?
(2x1)(x+3)4 < 1
You have four cases to consider:
(2x1)(x+3)4 positive or negative, and within those,
(2x1)(x+3) positive or negative
you will quite possibly end up with a solution set comprising 4 intervals 
still cant solve it.....
