@@arpan8584 Take the 4 from 4x and divide it by 2 then square it. It's completing the square in order to put it in the circle equation format. Same with the 1.
I wont use it in circles cuz there is a formula for it but i will use in conics to complete the square root....THANK YOU It will help me a lot in objective
A better alternative would be using the formula for radius which is root(f²+g²-c) where f is half of coefficient of x and g is half of coefficient of y and c is constant term. We must represent the function in implicit way to do so though.
Or: x²+4x=(x+2)²-4 y²-2y=(y-1)²-1 (x+2)²+(y-1)²=-1+1+4 (x+2)²+(y-1)²=4 (x+2)²+(y-1)²=2² r=2, centre (-2,1) Pretty similar, just a different perspective
Your approach to solving problems is very unique. Calm yet terrific...
Thank you
Sir tell full question review
1 and 4 coming from

@@mrhtutoring sir i follow you i saw your every video
2g= 4 , 2f = - 2 , c = 1
R = _/(g2 + f2 -c) = 2
You are a great help to us❤
Thanks
Pls use white chalk ....it will more visible 😊
Will do~
Love your method
Is it just me or is the audio slightly out of phase with the video? It seems to me that the sound of chalk is a couple milliseconds behind.

I don't know what happened, but I do know I can solve it within seconds in my head with a way easier technique x-x
Why don't you tell us your technique?
That's pretty good!

R = (g²+f²-c)½
My question is how is that equation the equation of a circle. That i can't rap my head around. Wondering if you can help.
I will try and make a full video on circle equations.
(x - a)² + (y - b)² = R², with the center being (a; b)
тыж красавчик!!! концовка огонь 🔥
I'm no math genius, but how is
xSquared + 4x +4 gives (xSquared + 4)Squared?
Shouldn't that be (xSquared + 2)Squared?
In the video, I stop at x²+4x+4 and not factor it to (x+2)² since we're only as to find the radius.
@@mrhtutoring Thanks, my bad, I watched the video again and noticed what you did.
Keep up the good work.
Thanks again.
@@userbasba My pleasure ~
Interesting
Or:
x²+4x=(x+2)²-4
y²-2y=(y-1)²-1
(x+2)²+(y-1)²=-1+1+4
(x+2)²+(y-1)²=4
(x+2)²+(y-1)²=2²
r=2, centre (-2,1)
Pretty similar, just a different perspective
