Solve the inequality by Case Analysis.
What is 'Case Analysis' ??
Have you noticed that on MA132 Foundations Exercises 1 there's a typo in Section A? 1 ii) doesn't make sense!
Anyway, plato was right with what he posted.
Remember to flip the inequality sign around when you take s as a negative.
If x is negative then multiply through by x and flip the signs around:
Then solve each separate equation:
When x is positive, just solve by splitting it into two separate inequalities like above.
Hope it helps!
