2.9 Solving quadratic inequalities

AQA Edexcel OCR A OCR B (MEI)
Quadratic inequalities are solved like normal quadratic equations, but with an extra step of drawing a graph to determine the correct region(s) at the end.

More complex inequalities involving brackets and fractions can be rewritten to linear or quadratic inequalities.
Important
When solving quadratic inequalities, draw a graph at the end to determine the correct region(s).
