What! why? All the Inventions are thanks to mathematics and physics, and they are a science that you acquire to become smarter and able to solve life issues.
Kinda hard , we're tought with deltha(∆) because is easier (8th grade student at a random college) For example: 12x²+3x+10=0 a=12x²=>a=12 b=2x=>b=3 c=10 Now delta formula: ∆=b²-4ac ∆=12²-4•2•10=144-8•10=144- 80=64 There are two posibilty with y, writed as y1, y2 The formula for y1,y2 y1;y2=-b±√∆/2•a =-3±√64/2•12 =-3±8/24 Now for ± will be dived in (+)for(y1) and (-)for(y2) y1=-3+8/24=*5/24* y2=-3-8/24=*-11/24* and there will be smth like(x•y1)(x•y2)=0 (x•5/24)(x•(-11/24))=0 And that's it pls if any math experts are here tell me if I did it right cause I only got 9 in math class and mom thinks I'm a failure beacuse I can't get a single 10😭
These are the moments when I totally regret the lack of attention I put on my classes a few years ago, Thank you miss!.
Thanks! With this it only took me twenty seconds to solve the question I was stuck on. :) (SYNTAX ERROR) My grading teacher will be proud.
Parabéns tia. Muito bom. Gostei. melhor do que a explicação dos professores brasileiros.
I hate math.
😔
Yup.

Well that doesn't mean it's easy or fun
That sounds like a you problem
Kinda hard , we're tought with deltha(∆) because is easier (8th grade student at a random college)
For example: 12x²+3x+10=0
a=12x²=>a=12
b=2x=>b=3
c=10
Now delta formula:
∆=b²-4ac
∆=12²-4•2•10=144-8•10=144-
80=64
There are two posibilty with y, writed as y1, y2
The formula for y1,y2
y1;y2=-b±√∆/2•a
=-3±√64/2•12
=-3±8/24
Now for ± will be dived in (+)for(y1) and (-)for(y2)
y1=-3+8/24=*5/24*
y2=-3-8/24=*-11/24*
and there will be smth like(x•y1)(x•y2)=0
(x•5/24)(x•(-11/24))=0
And that's it pls if any math experts are here tell me if I did it right cause I only got 9 in math class and mom thinks I'm a failure beacuse I can't get a single 10😭
Thank you very much. I loved!
Does the box method always end up with right solving ?
Thank u ☺️ can u please give me the video that u explain the box method ❤️?
this is not second degree, this is multistep with sqare roots
i'm in 10th grade and i literally forgot how to solve equations, thank you so much. i am going to kill myself.
What grade math is this??
Thank you, professor, to follow you up from Iraq
Professor?????
got it very clear and understanding
thank you so much for this video, I really learned how to solve the second degree equations
This is a hard step but i will try my best to achieve this style
how do you solve with a prime number
X^2 +4x-5=0
Sorry that i am too late😅, but you can use (x+5) (x-1)=0
@@jetmirahajdari4686 just a bit. Thanks tho
I solved your 5 min I solved 5 sec the question is insoluble
tek türk değilmişim :)
I think -b±root of b square - 4ac/2a is better
Just use Diakrinousa
شت
in the comments there all turkish ppl me too!
This confused me even more
