How do you find the x and y intercept of a quadratic
👉 Learn about the parts of a parabola. A parabola is the shape of the graph of a quadratic equation. A regular palabola is the parabola that is facing either up or down while an irregular parabola faces left or right. A quadratic equation is an equation whose highest exponent in the variable(s) is 2.
The parts of a parabola include: the axis of symmetry (the line passing through the vertex of the parabola to which the parabola is symmetric about), the vertex (the point at which the parabola turns), the domain (the set of possible x-values of the parabola, usually all real numbers for regular parabolas), the range (the possible y-values of the parabola which is usually the region above the vertex inclusive or below the vertex inclusive for regular parabolas), the x-intercepts (the points where the parabola cuts the x-axis) and the y-intercepts (the point(s) where the parabola cuts the y axis.

I want him as my teacher. Having a lesson then being able to look back at it. That’s pretty neat

Your videos are a God-send. Thank you for being so thorough with your explanations and examples. My 7th grader is taking advanced Math and as an online learner to boot. I'm pretty good at Math but it's been a minute since I took Algebra. My son wishes you were his math teacher.
Thank you so much! I honestly cannot express my gratitude for this! You are a god among men sir!
Whoever is in your class must be blessed to have you as a teacher. I have a teacher that has been teaching math for over 27 years and he still does not know how to explain properly. Thanks alot man! :)

I always go to these videos for help. Thanks so much!
i have watched so many of your videos and you cover everything i need help with perfectly
So for the “factoring” part of the x-intercepts did you just add X to a and X to c if so what happens to b?
Thanks so much, this actually really helped. I've never really seen a math teacher who can explain math so well, lol.

Mr. Logan...I really need your help. If my quadratic equation is x^2-4x+5....how can I figure out the x intercepts? Positive 5 does not have two numbers to make it positive five and also equal -4. If I take the entire equation and multiply it by -1, then -x^2 will still not come out correctly.
Thanks for posting all your videos. I'v been binge watching these things, a day before my exam, because I've forgotten how to do all of it.

but what if i have something like 3x2( three x squared) instead of just x squared?
how will you know if you don't need to find the x intercept since there are some parabolas that don't cross the x axis
Thanks for explaining it
This guys a life saver. I do independent leanring (To sum it up quickly, I have a book and teach myself, but still have access to school resources) anyways, I took a month break and forgot a lot of stuff and i have misplaced my notebook for math, so this guys a big help. Thank you!🙏
Oh now I understand it multiplies to 4 and it adds to 5, see this is the Part of the factoring that I needed to know, and Brian McLogan really nice job solving it using your brain. To be fair it was pretty easy. But the thing is there is factoring problems that are so hard to factor because they include really big numbers. There’s probably a video out for it, I’ll check. Thanks for this video, it helped me.
