To be able to solve quadratic inequalities algebraically. The lessons are split into 3 sections: A recap of solving linear inequalities. Solving simple quadratic inequalities. Solving harder quadratic inequalities that involve rearranging and factorising to find the critical values. For more Algebra resources visit www.themathsgeezer.co.uk
You can use the quadratic equation to find the endpoints of the intervals that will be you solution, and would then need to test in which of those intervals the inequality is true. So in this case you could use it to find -5 and 2 [ (-3 +- Sqrt (9+4 (10)1))/2 = (-3 +- 7)/2 = -10/2 or 4/2]. This breaks up the number line into 3 intervals {x<-5 ...
