Mr. Mclogan, you will be the reason I pass pre-calculus in college. Thank you. I have been struggling to learn the material in my university's online learning platform, Mobius. It's very vague and will give an example problem and then ask to solve a question that it barely gave an explanation on how to solve in the first place. Your videos have taught me more for my pre-calculus class than Mobius has these past 5 weeks. So again, thank you for helping me pass my course and eventually earn my degree.

I really appreciate this video, especially of how you were able to explain the complete the square function.

This is a life saver.

An easier approach is to divide 4x and -10y by (-2).. you’ll get (-2,5). Then you square root (-2) squared plus (5) squared - (-7) which will give you 6. Square the 6 and you’ll get 36. Now just put them in your equation. So it’s gonna be (x+2) squared plus (y-5) squared equals to 36.
