SOLUTION: Solve and graph the solution of |3x-7|greater or equal to 23 (X-1)(x+3)(x2)<0

Question 971163: Solve and graph the solution of
|3x-7|greater or equal to 23
(X-1)(x+3)(x2)<0
Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website!

Use the two possible conditions for your absolute value inequality. Either 3x-7 is non-negative or it is negative.
Solve according to BOTH of those conditions. You will have the two equations:

The next inequality should be examined for signs of the four critical values which make the
intervals on the x-number line. Less than zero means negative; not less than zero means non negative.
Part of inequality is not written properly, so assumed to mean .

Pick a value inside each of the intervals: , ,, .
