You just saved my Algebra exam, you're amazing

[@MichelvanBiezen]

Glad you found our videos and we were able to help. 🙂

[@samairadhanrajani445]

this is by far the only video that helped me understand the concept without confusion, thank you so much (:

[@MichelvanBiezen]

You are welcome. Glad you found our videos. 🙂

[@dominikaandglebshchemenok1384]

Couldn’t remotely comprehend the question before this video!!! My main teacher has gotten sick for 2 months now and our relief teacher did not cover this topic at all, but still expects us to know what to do… Thank you so much again!!!

[@MichelvanBiezen]

You are welcome. Glad you found our videos. 🙂

[@linzixuan29]

Mine too

[@ethan-zq6kx]

THANKS A LOT!! OH MY GOD I AM SO LUCKY TO FIND U ON YT, UR VIDEOS ARE AMAZING!!

[@MichelvanBiezen]

Glad you found our videos. (There are over 10,000 of them.) Thank you for liking them.

[@bella1faux]

Omg!!! Thank you so much I was so confused in my algebra class cause the professor was skipping steps now everything makes sense!

[@MichelvanBiezen]

You're very welcome!

[@Bizzwave_05]

finally I understand in this video now its easy for me sir you make my day my language is different but I did it / respect from Turkey
🤩

[@MichelvanBiezen]

Thank you . Welcome to the channel

[@pieontoast_23]

Thanks heaps for making this! i missed a few classes and was way behind, this video is easy to understand and to the point, unlike my maths teacher sometimes!

[@MichelvanBiezen]

Glad it helped!

[@muna-zu4ct]

I swear to god I understood this so fast then in class thanks so much man

[@MichelvanBiezen]

Glad you found this helpful.

Lifesaver sir! Thanks 🤟

You're welcome

[@Dem0nDays]

Yes! Amazing job. Im taking an online precalc and it's missing that personal touch.

[@MichelvanBiezen]

Glad you found our videos. We also have precalculus videos as well.

[@uejsgsjsgajdtahsvsjwy425]

So my given was -x^2-4x-5, does that automatically mean its a0.. what could i have possibly done wrong? :(

[@MichelvanBiezen]

Was it given to you in the form of an equation? y = -x^2 - 4x - 5 ? This graph opens downward. Note that - (5)^2 = - 25 and - (-5)^2 = - 25

[@uejsgsjsgajdtahsvsjwy425]

@@MichelvanBiezen i just fixed it, i accidentally made the -4 a positive 4 while solving for h 😅😅 now its opening is downwards, thanks so much for replying 😁

[@frozenh2o984]

You are a lifesaver , W person

[@MichelvanBiezen]

Thank you. Glad you found our videos. 🙂

[@lukangeI]

I LOVE YOU SO MUCH

[@MichelvanBiezen]

Thank you. Glad you found our videos. 🙂

[@ramisaafia421]

Thank you soooooo much! I was stuck on a question exactly like this. I was afraid my mom would get mad because I was doing my assignment in the last moment. This video made me understand my work and now I can do it in just a few second. You just saved me.

[@MichelvanBiezen]

Glad you found our videos. Next time don't wait till the last minute (that is what I do and it doesn't work well). 🙂

[@ramisaafia421]

@@MichelvanBiezen sure thing I’ll remember that for next time thanks for the advice! 😄

[@henrykelsey4936]

If b is negative does it change to positive or stay negative

[@MichelvanBiezen]

It depends on the value of the other two constants.

[@Betsy-cq7bx]

Positive I’m pretty sure

[@bigdog3628]

son of a gun I thought the a Value had to be positive, so I divided the whole equation by -1. Got the same numbers for vortex, just wrong signs. (I only watched as far as figuring the vortex.)
edit I fully watched, and yeah the step I took that messed me up I would only take if completing the square to solve for the x values. Cool video and love the bow tie. (reminds me of my dad he always wore one and was a great man)

[@MichelvanBiezen]

Glad you figured it out.

[@Slorshatron]

What if you cant factor it

[@MichelvanBiezen]

Then you have to use one of the many other mathods to find the roots. (shown in other videos on this channel)

[@Mikenab1979]

How is -(4) became positive?

[@MichelvanBiezen]

If you are referring to the first line. we have -4 / (2)(-2) = -4 / -4 = 4/4 = 1

[@Lorenzo-tm8dn]

Nahh my boi u saved my ass thanks

[@MichelvanBiezen]

Glad you found our videos and you found them useful. 🙂

[@stoopidyash]

Thank you a lot sir, I was troubled by the maximum height achieved by a rocket sum and i needed to find it by using an equation, i was able to solve it using your video.

[@MichelvanBiezen]

Excellent. Glad you found our videos. 🙂

[@sassyqueen9739]

2•-2 is -4!

[@MichelvanBiezen]

The negative cancels out with the negative in the numerator.

[@Lau-ds1dv]

blud wheres the x-intercept?

[@MichelvanBiezen]

The y-intercept is 6 (when x = 0) as shown in the video.

[@FutureBILL]

Blud

I don’t think he gets the point
