"How to Solve By Completing the Square (NancyPi) MIT grad shows the easiest way to complete the square to solve a quadratic equation. To skip ahead: 1) for a quadratic that STARTS WITH X2 skip to time 1:42. 2) For a quadratic that STARTS WITH 2X2 3X2 etc. skip to time 6:46. 3) For NEGATIVE leading term like -X2 skip to 13:34. 4) If there's NO X TERM (ex. 3x2 - [---] = 0) then you cannot complete the square and can solve directly - skip to 16:30. Nancy formerly of MathBFF explains the steps. Follow Nancy on Instagram: https://instagram.com/nancypi Twitter: https://twitter.com/nancypi How to"

"How to Find the Horizontal Asymptote (NancyPi) MIT grad shows how to find the horizontal asymptote (of a rational function) with a quick and easy rule. Nancy formerly of MathBFF explains the steps. For how to find VERTICAL asymptotes instead jump to the video: https://youtu.be/V137qmDN9Qw Follow me on Instagram https://instagram.com/mathnancy Follow me on Twitter: https://twitter.com/nancypi The degree of a function is the highest power of x that appears in the polynomial. To find the horizontal asymptote there are three easy cases. 1) If the degree of the numerator expression is less than"
