These videos never seem to age. Even two years later, it has helped me immensely. Thank you, Jen.

Please make a completing squares detailed video as well. I really appreciate the way you start the topic from the base because students like me who are new to all this really wants to learn from the scratch ! Thanks

ISTG YOU ARE THE ONLY PERSON WHO EXPLAINED IT VERY SIMPLE THANK OYOUYOU

[francaellerman]

If you already know the forms of a quadratic you can probably skip to 4:29 .

Thank you for the video! This type of question is worded very weirdly so your breakdown was very helpful.

thank you this was very helpful, I was doing khan digital sat prep but I couldn't figure out the constants or coeffiecients or what they were asking me

[alihazem]

This is the best video for this subject. Thanks 😀

[docomocco]

I was not able to get through these types of questions but JEN you made it so easy now thanks!!

7:41 thank you so much Jen I was doing pretty bad on the Khan academy practice for this because I had no idea and I was so lucky that you were the first person I watched

[anisha]

Best video I found regarding parabola ♥️

In Example 3, I think it's easier to use -b/2a to solve for the x-value of the vertex. Since the equation is already in standard form, we see that b = 2 and a = 1, so -b/2a = -1. Of choice C & D (the only two in vertex form), only choice D has an x-intercept of -1 for the vertex (choice C has the wrong sign). Most of my students prefer not to complete the square if they don't have to!

[saalsalih]

Your vid helped me thank you please do more vidioes like (completing squares ):🧡

For the last question
Can you explain why the D is not right please
