Hi,
I'm Ai Ling. I enjoy coaching students who have challenges with
understanding and scoring in 'O' Level A-Maths and E-Maths. 
Very good video for students to learn Quadratic Equations, as well as a teaching tool for teachers and tutors. Keep sharing! I will share this video blogpost with my readers.

k < 3
Glad you have shown a better way to avoid the above error.
Thanks

Much appreciated post. I find that even when I point out those mistakes, there’s still a large percentage of students that make them.
