Complex Quadratic Equations | O Level Additional Mathematics

This video shows you how to solve more complex quadratic equations (where substitution is used in order to derive a quadratic equation).
My videos cover the O Level Additional Mathematics Exam syllabus.
I hope this video helped you, and if it didn't, constructive criticism is appreciated.
More content is on its way.

At 10:10, the answer should be x = 2, not x = 4. It looks like I made a mistake when writing my final answer, but the work leading up to it is correct. I’m sorry about any confusion this may have caused.

10:10 I attempted the equation and got x = 2 instead of x = 4 , why?

[@IbrahimIrfanullah]

Thank you for pointing that out! You are correct. The answer should be x = -3 or x = 2. Looks like I made a silly mistake when writing the final answer. I apologize for any confusion.
