12 - Factoring Trinomials & Quadratic Polynomials in Algebra, Part 1 (Learn How to Factor)

In this lesson, you will learn how to factor trinomials and quadratic polynomials in algebra. We explain the method as the reverse of the FOIL multiplication method.

You will learn how to examine each term and determine what can be multiplied together to get that term in each part of the expression. Finally, we must choose the correct signs in order to make the inside and last terms add correctly.

You will learn how to factor polynomials (trinomials and binomials) in algebra by solving problems step-by-step.

I must say that, your students are blessed to have you!

This man is clutch. Im 23 and studying for the SAT after 5 years in the military. He's getting me on track very well as I supplement these videos with Khan Academy. Thumbs up for him!

The way you explain things is very helpful

I have been trying to teach myself this math for so long and every time I tried I got frustrated and gave up. My learning style is much different than others and these videos seem to be the only ones that I actually understand. Thank you for going in-depth and really teaching! I think I’m finally getting it!

Thank you so much! I am eternally grateful for this video. I always have had issues with understanding factoring in polynomials and algebraic equations, but somehow you made it super easy to understand! I am so happy right now!

I just got through Algebra 2 and am taking the summer off now to thoroughly review before Precalc. 1 begins in the fall semester. Looking back at this lesson really makes me appreciate how articulate you present the material. It makes all the difference for someone looking for help. Many thanks to you!

You TRULY are an exceptional teacher man. I am 60 years old, did lousy in math all through school, and now in my old(er) age, I have you teaching me, and I AM LEARNING the math I always wanted to KNOW! You just have NO IDEA how grateful I am for your efforts, AND how GREAT it is to learn the math I have fantasized about knowing ALL MY LIFE. And I'm much older than you and many in your audience, and I am GETTING IT! ***THANK YOU***

U r such a good teacher. Too good. Thank u for didcating ur time with us. Very helpful.

Initially, it seemed very tricky and hard to understand but with little practice and logical thinking it became meaningful and easy to understand. I'm grateful to you cause you make us understand maths in a easier and meaningful way!

Great content. After doing a few problems you can get to the point where you can factor a quadratic in your head. Just think what factors of the constant will add up to give you the correct middle term coefficient. So if you have a constant of +8 and -9x middle term, then the factors -1 and -8 will give you a positive constant and the correct negative middle term.

Thank you so much sir! Mathematics is not a difficult subject just that we have poor teachers/lectures who doesn't know how to teach. I'm following all your videos and so far so good 😊👍. I can proudly say I'm doing better in mathematics than I was before.

I’ve been studying for my ged and always struggled with math. I subscribed to your website and you sir are awesome at explaining and giving problems. Thank you.

[Cupcate_ykew]

Thank you so muchh, I was struggling so badd in this topic, explaining it properly especially when I'm an auditory learner, have a great day

[cool_kidFF]

my teacher introduced us to factoring polynomials a few days ago, and I was totally and utterly lost!! I have a test tomorrow, and my last ditch effort to understand was youtube. I stumbled across this video, and I went from "what do I do" to "oh I get It now!" this video was super helpful, keep up the great work!

[gundalalebona]

Wow Jason you are a life saviour. Your teaching methods makes learning Math very enjoyable more than understanding.

Thank you so much sir, really appreciate the way you explain in details!! it's really helpful, thank God for people like you❤😊

[chuckteixeira]

Your videos are the best I've encountered.

I was stuck on this so hard I felt like I was an idiot for not understanding something seemingly so simple to others but my goodness you have such a talented way of conveying the message in such an easy to understand way
