Fnished high school 20 years ago. Studied humanities and worked for 17y, changed fields and now back at school, taking math refresh course. Didn't understand factoring back then and didn't understand it for the past 3 weeks... You saved me! thank you so much. It's not just the teaching, I know video editing is time consuming!! Thank you so much!!
I have watched almost everyone on TikTok try to teach me how to do this. I finally found you and your voice is truly so calming, and it makes me feel so calm during a stressful time at exam week.
I think, out of all the maths channels, NancyPi is by far the best! She talks through it step by step which allows you to actually keep up and understand it. Most maths channels dive straight in, go far too fast and don't talk through it step by step. Keep up the good work!
Wow... 27 years out of school and this FINALLY makes sense! It didn't help me any that my instructor didn't speak English very well. When being taught the art of solving "quadratic equations", we were all just staring, glassy-eyed at the board while our instructor droned on about "quad-e-reddic eck-wishuns". Thanks for making this look easy.
I really love your channel and it really helps me because I know it may seem like a small thing, but I like how we’re able to see a person and not just hands writing, because I take in a lot when I’m learning. I can visually see you writing and I can also see words coming out of your mouth which doubly cements the information I’m intaking so thank you so much for that. I also like your setup with that clear board and honestly even the pink color keeps a girl like me engaged, who is allergic to math. Thank you for all your videos that are concise and gentle. I’m taking calculus again which I failed and I’m hoping to really make a comeback. You videos give me hope. Thank you.
I like the way you talk , its like super quiet and gentle, contrasting from a BUNCH OF MATH TEACHERS WHO BE Screamin, thnx to you I'm finally getting this!
It is now 1pm in the afternoon. I have been sitting with this lesson the WHOLE day, and only after watching this did I finally get it. Thanks a million, Nancy, you saved me from Mathematical embarrassment! Love from South Africa...
Thank you for making these videos, they are incredibly helpful! I'm studying for the GRE and I haven't done this kind of math in probably about 6 years. You are really good at teaching and any student would be lucky to have you!
This was a life-saver. I always wondered how my Ti-36x Pro did it... But now I can do it without its number solver. Thank you very much for taking out your time to show us the steps!
My degree is in English Lit (1976) because I never could follow math once I hit Algebra II. I wish I'd had you as my teacher. Thank you for what you've taught me so far. Please don't stop.
After two days of frustration, you saved me. I couldn't understand how the teacher was getting her answers and the books not really making it too clear. You are amazing!!! Thank you!!!!

Studying for a college placement test since I haven't taken a math course in 4 years. This was incredibly helpful! Very easy to follow along and understand. And that Magic X method is amazing! Thank you!
Girl you saved my life. I literally have a math test abt this but w a graph and asking for more depth in questions but this is sm better than what my math teacher taught me in 4 days😭
Yes it did! This video did help, because I was never taught this simplified X-method. Now, very difficult quadratic equations can be solved much easier. Thank you!
Any of my math teachers through high school or my first college and now my second college haven’t ever shown me that X way that you did . That was very interesting!
Hi Nancy just want to say i love you and your videos so so much, they have helped me so much. I'm in a rehabilitation center at the moment and I'm trying to get my grade 12 and you've given me hope.
Beautiful and brilliant NancyPi's Magic X method for solving problems like 3x²+14x-5=0 is best if it's a fill-in-the-blank question. However, if it's a multiple choice question such as on the SAT test, the Sums and Products Method is much faster, easier and less error-prone than the Magic X Method. In fact, the solution can be calculated in your head in just a few seconds. Step 1: Divide the second number (the coefficient for x) by the first number (the coefficient for x²) and change the sign. This number is ALWAYS the SUM of the roots. Here that number is -14/3 or -4 2/3. Step 2: Examine the 5 possible answers to determine which roots when added equal the number from Step 1. If there's only one match, that must be the correct answer. If there's more than one match, perform a second calculation to determine the product of the roots to eliminate any duplicates. For that calculation, divide the third number (the constant) by the first number (the coefficient for x²). Here that number is -5/3 or -1 2/3. You can also perform the multiplication calculation first. In fact, it's best to do so if the last number (the constant) is an even number when divided by the coefficient for x² and not a fraction as in 3x²+14x-6=0. Here that number, the product of the roots, is -2, an even number which is easier to work with. To find the answer even more easily, I would first glance at the five choices to determine if any of the answers have root sums that are equal. If not, I would know the multiplication test is not necessary because there are no duplicates among the sums. To summarize, the roots for 3x²+14x-5=0 are 1/3 and -5, the sum of the roots is -4 2/3 and the product of the roots is -1 2/3. The salient point is multiple choice questions should be approached differently than fill-in-the-blank questions because finding the four wrong answers is often much easier and faster than finding the one right answer the long way.
Why am I watching math? No idea but it's really relaxing. You should seriously consider doing ASMR math...you have such a soothing voice. Thanks for the content Nancy!
At 6:13. I use a slightly different method. Using your example: 1) mult. coeft of x^2 by const.: 3 x -5 = -15. 2) Find factor pairs that sum to coeft of the x-term: -1 and 15. 3) Re-write the original equation using -x + 15x (found at .2): 3x^2 - x + 15x - 5 4) Place brackets around the first two terms and again around the next two terms: (3x^2 - x) + (15x - 5). 5) Factor these brackets: x(3x - 1) + 5(3x - 1). Note: the two bracket MUST be the same, else you have made a mistake. 6) Put the terms outside each bracket, i.e. x and 5, into one bracket, (x + 5); the other bracket is already done, (3x - 1). 7) Put these brackets together: (x + 5)(3x -1). giving x = -5, x = 1/3. It may appear difficult but this is owing to the format here. Try it and you will see it is much simpler. In my view at least. :)
