Let me know if you need more explanation. I assume you have learnt how to solve quadratic inequalities.

Would you be able to solve this without using quadratic inequalities?
There is a Sec 4 A Maths approach for this, but you have yet to learn this and it’s Super complicated so the only other way to go about doing this question is to reduce the question to an inequality.
In short, you can only do this question after doing practice on quadratic inequalities. Your teacher should not give you homework on this if you have yet to learn quadratic inequalities.
