At last someone clever that knows how to explain what is regarded a bit difficult. Brilliant explanation. Thank You.

I didn't think I would ever understand how to use the quadratic formula until I found this video, thank you for explaining it so well, it's not easy but this is where you understand the concept and then work from there to make it easier for yourself, practice makes things better.

i learn this 35 years ago from a classroom but understand nothing. by now, after watched this short video make me fully understand it is not too hard indeed, thank you Sir.

Thank youuu 😭😹

This is the method we learnt yesterday with our lecturer, I hope it gonna be asked in the exams, then I'll surely nail it, thanks so much.😊❤

An hour of trying to understand compare to a 15 minutes video. Thank you so much, you help me a a lot sir.

I think the simplest way by some margin is to multiply 10 by -3 the find the 2 factors of 30 that combine to make 13, ie 2 and 15, giving (x - 2)(x +15) now, the clever bit is just to divide the 2 and 15 by the 10 , simplify and allocate the denominators to the x terms giving (5x - 1)(2x + 3). There is a YT clip on this.

I studied maths at school many years ago, never found it easy and have forgotten so much, so this is helping me gradually understand again.

Thank you so much sir. I had a hard time understanding quadratic equations, but now its the easiest lesson for me....😊👍

the way you explain it makes solving these equations makes it so easy to understand!

very excellent explanation where even a slow leaner can get the concept very fast thank you so much

God richly bless you sir I never understood this concept in class for a year now :)

best explanation ive seen yet. thanks!

Excellent video tutorial! Thank you so much.🙏🏽

I love 3rd method, and also love you and your approach. 💞💞💞

Thank u so much sir. I had a hard time understanding quadratic equations, but now its the easiest lesson for me....😊👍👏

I just found this video and it really helped me a lot learn this in advanced!! Thank youu!!! 🙌

I just knew there are three ways to solve the quadratic equation. Thanks

than you very much this is the best teacher i have got

well explained and much appreciated.

Thank you so much!!! This is amazing! 🤗

Well explained... Thank you. I recall when I was a student and how interesting this subject was...

Wow I finally understood completing the square method

❤thanks very much sir, I am so grateful for your help❤

I have never understood but now i have got it💯👍

Do we have to multiply by 2 and take square always?

Thanks so much ,it is been very difficult for me at school ,I think I understand a little 😊

Thank you so much sir I got something reasonable here

Thanks your a lifesaver

Very nice explanation Sir

Sir, your method of teaching is really understanding.l just wish l could send some questions which are so tricky.

Thank you sir

Nice lessons sir enjoyed it

Bravo ! Sir , help us on sequence and series please.

hello i really like the way you teach thank you

THANK YOU VERY MUCH SIR . THE 3RD METHOD WAS BIT DIFFICULT TO ME . I GUESS IM GONNA USE THE FIRST 2 METHODS IN THE EXAM. ANY WAY THANKS AGAIN FOR THE GREAT VIDEO

I basically needed more illustrations on graphical method of solving quadratic equations

I think the sign is is important. It should be 10x(-3)=-30 such that - 2x15=-30. Otherwise one could also take 10x3=30. 10+3=13 too.

I am glad there are now many easy ways to solve for the trinomial, good for the students . But actually, in real life, this kind of math is of no use! Actual situations are much more easy if one just have a common sense!

Nice, waaaooo, best teacher

I always find completing the square amusing, when you get the horrific looking fractions like 289/400 during the working out.

Thanks you sir I was having hard time with completing the square

Sir you're the best

Why we used 30=2*15 then -2 +15 and not 30=3*10 then +3+10 how to choose thank you.

either 3 or 10 had to be negative..not both positive which is the only way to get 13 your way

-1/5 and 3/2 .might I'm right .cause completely confuse sir .please make sure how you did it.thanks

kindly tell me which way to choose when I see a quadratic eqaution?

Dear Andy, if I were in your shoes I would definitely try factoring method first. If factoring not feasible, then go for Quadratic Formula. However, Completing square method is a very powerful tool used in applications! Thanks for asking😀 I'm sure you are a brilliant and bright student 👍 Please keep sharing my channel with your family and friends. Take care dear and all the best😃

With respect, calculate the discriminant first. That will tell you if: --- it can be factorised (the discriminant will be a numerical perfect square), or not, or --- if the quadratic is a perfect square ( ie b^2 - 4ac = 0), or not . Completing the square on 10x^(2) + 13x - 3 = 0 is unnecessarily difficult/complex, since the quadratic can be factorised.

Amazing

who are you guys on this youtube factorising 10x2 +13x -3 as (10x-2)(10x+15)?

And also can u pl explain about plottings

😊😊😊 very nice and beautiful ❤️

very good

Thanks so much i was green about this but am now ok

Make more videos about quadratic equation

After 11 minutes in the video when the left side becomes a complete square what happened to 13/10x in the equation ... X +13/10 + (13/20)*2

Why not 3 times 10? 10+3 is 13?

10 x 3 = 30 = 15 x 2. Hence 1/10 (10 x + 15)( 10 x - 2) =o . Hence (2 x + 3)( x - 1) =0 so x=1 and x = -3/2 = -1 1/2. PSD.

Why divide by 2 in completing the square

What about 13÷10x ..how it is romoved

If the coefficient is small, example 3.

👌👌👌💫

#crossmultiply #crossmultiplication #crossmultiplying

good

Thanks from a dad trying to help out his boy

#binomial #linearequation

Please rectify my last step. Factors were (2x+ 3)((5 x-1)=0. Hence x = - 3/2 = -1 1/2 and x = 1/5. PSD.

Pritam Dhinsa ji, you are right on. Cheers :)

Wo😂😂😂 the best

how about the X method can u make video too? thanks

The leading coefficient does NOT have to be 1. That is false. In fact, it is easier to complete the square in this case by multiplying through by 40 (thus avoiding fractions). So 400x^2+520=120 , now our first coefficient is also a perfect square (20x)^2 and the 2nd coefficient is an even number. So (20x +13)^2=289 Easy.

Sir in your factoring 10x . 10x is 100x^

Why not 10+3 and 10*3

Why did he not use 3 and 10 as factors of 30. When 10*3 = 30 and 10+3 =13 ????????

@-okCat-

because the 3 was negitive. 10 x -3 = -30 and that would not work if you used 10 and 3

5x - 1 = 0 5x = 1 x = 0.2

2x + 3 = 0 2x = -3 x = -1.5

(2x+3)(5x-1)

You can't leave -3 over 2 bro that's an improper fraction 😮
