How to find the center and radius of a circle in standard form

It is still helpful even after years later, like my teacher would keep talking too fast and before you know it there's like a bunch of equations,number, fractions written and I leave myself clueless and this guy makes it easy to understand within minutes bro... Man to have this teacher would literally make me ace math easy.

This guy is an angel sent from heaven 😭
If only my teacher explained these as thoroughly as he did

Thanks alot

Question how did the (x+2)²+(y+5)² become -2,5 should i just switch their sign?

Can someone help me with this math problem so i can move on
X^2+y^2+6x-10y+40=0

And when i solve it the radius is 0
I know theres something wrong about my answer in radius. So i just wanna know if im right or someone clarify me about this. Thanks!

Omygosh! you're a savior sir😭

Thank you so much ❤

Helping me clutch math Fr Fr

thank you very clear explanation!

What do you do if you got decimal point by dividing by 2?

Thank you so much for these videos, im starting precalc this year and needed a refresher on some algebra and this really helped! I keep blanking on some of these things lol

10 years later, after studying with you during my middle and high-school, now i am studying for my uni test with your videos as well ❤️ I hope I can come here again during uni, you’re the best teacher out there for math

thanks randy orton

Thanks man! I have my algebra 2 honors exam tomorrow and these videos have been super useful for review

Has anyone ever told you that you sound exactly like the comedian Ryan Long?

you are my internet friend!!!!

Thank you so much for all your videos. They have really saved me in my homework.

Ye to Johny sins hai 😂 ab teacher v ban gyea

Im a little confused on the last step was hoping someone could explain where the -10y and 4x went

Dude you teached me so much better than my classmate who wanted to teach the subject but got the class more confused

thanks brian ur a real one

This is amazing 💪

Thank you so much

YOU ARE A HERO!!! I have a test on this and I was so confused lol

I have seen 5 to 6 videos but no one was able to understand like you, you have told in a very simple way, your method of teaching is very good

this was honestly perfect thanks

all this is sooo confusing. i’m an eighth grader doing this 😢 but you made wayyy more sense than my teacher

Thanks for this☺

Thanks

The goat

Thank you so much! :D Couldn't have made it through my midterms without you!

at this type of question if the general equation of circle is given x^2+y^2+2gx+2fy+c=0
center of circle is(-g ,-f) and radius is square root of(g^2+f^2-c)

I have been studying weeks for a test and failed (68%). I watched your video and studied with your method and retook it 2 days later, got a 86%. you sir are a life-saver.

Ur the best ❤️

Can't believe good math teachers like you exist, good work

this doesn't seem right as -10 /2 squared wouldn't make 25 it would make -25

Thank you so much Mr. McLogan!

excuse my language but,
FUCK ALEKS!
God. That program could make a mathematician hate math.

How do I do the reverse? Find x^2+y^2+ax+by+c=0 when I have (x-h)^2+(y-k)^2=r^2

Idk why this man can teach me a math problem in just 10 mins 😩💅

Thank you.

whaddup Brian! Yet again carrying me through College!

I know this video was recorded more than 10 years ago. It is very straight forward. However in the last minute of the video the teacher mixplace the results. Why he put the center (-2,5) when in reality it was (2,-5). The 5 was negative not the # 2.
X= 2, Y= -5. Can you correct it in a new video if you can? Thanks.

As a british student in a completely different education system this helped quite a lot, one thing though, instead of making it a trinomial, why not just complete the square and add the integers of 4 and 25 produced from those squares onto the other side, along with the 7, to me it seems like an unnecessary step including a trinomial but if it works it works😂, thanks for the video.

Cramming for an honors geometry midterm at the moment...as a current freshman who took algebra last year, thanks, this really helped me remember what I learned! 😅

To shorten it even more just half the number and change the sign. Your welcome

this is a freaking gold mine
