This is number 3 in the Inequality series. Just a bit harder than number 2. Pause the video and have a go!
An inequality is solved with x' in the denominator. 
With an inequality with 'x' or an expression of 'x' in one or more than one denominator, the technique used is to multiply both sides of the inequality by the square of the expression in the denominator. This process will not affect the inequality sign since you are multiplying by a positive number. Then this allows you to cancel the term in the denominator. Next, the inequality must be set up so that the expression on the left hand side is always greater or less than zero.  The  expression is then factorized and the values of x that make the  expression equal to zero are then obtained. These values are then used to determine the region(s) in which the inequality is valid.
