  1. 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.


  2. Many of us forget to change the inequality sign when we arrive at this stage

    -12k < -36
    k < 3

    Glad you have shown a better way to avoid the above error.


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