How to Factor and Solve Quadratics - Sneaky Trick - No Fuss Factoring

[rakshith]

sir, ur video helped me very much, i was soo confused and i love ur voice

[Prof.Polymath]

Remember this from my days in the college of knowledge. Mr McCann ! Fantastic teacher !! One of the best !! 👍🏼

Sir how will we come to know..which factors to take?...coz for 12... We could have also taken 6x2...and for 72...12x6..bt when I multiply...2x12 I get 24 and not 27...so how will we come to know...which factors to take for a given number?

Thank you so much sir, I’ve had all teachers explain, watched a lot of YouTube videos before coming across this, and I understand yours only❤

That trick is "automatic". You take the least multiples of the two numbers. Consider in each branch exactly the first from the left is the largest and the second from the left in the same branch as the smaller. Do it in both branches. Afterwards, do exactly that subtraction in that designed order between the branches using that internal and external arcs. This method is amazing. The rest is just to reduce the coefficients using gdc to decrease long arithmetic. It is the fast method ever.

I love doing quadratic equations. My favourite method is making the square because one has to keep juggling numbers around, but factoring is fun, too. Using the formula is quite boring by comparison. Thanks for posting these lessons sir.

Wow, that actually worked. Ive been stumped on a problem for about an hour looking how to solve big numbers like this.

[mahussein]

Thank you so much . Really, the way you explain is very clear and easy to follow . I have benefitted from you tremendously. Indeed you deserve millions of subscriptions, and and I am sure you make an immense difference in my people's lives .

You're so good no confusion in teaching.

Polite clear and very impressive way with patience I did Math at Secondary Level nearly 40 years Back Home Thanks I understood a lot especially your slow slowly way of communication Happy New year and best wishes for you and your family

We are looking for two numbers a na b, such as a*b=12*72, and a+b=-59
a+b<0 and a*b>0 so a<0 and b<0.
We know that: 12=3*4 and 72=8*9.
4*8=32 and 3*9=27
32+27=59
a=-32 and b=-27

3x-8=0 or 4x-9=0
x=8/3 or x=9/4

Well explained through out solution step by step. The critical point he shows is, how 59 to be the part of the quadratic equation that not rocket science. But use little brainstorming puzzle - two numbers are there.
He just factored them; 12 = 3.4 & 72 = 8.9
Figure out - 59
Only way, -27 & -32
-27 +(-32) = -59

[dinopad]

When you factored 12 x 72 as 4 x 3 x 9 x 8, there was no explanation why you didn't use 2 x 6 x 3 x 24, or any other set of factors... what's up with that?!?

[harsheilamahadev]

Thank you. I was very irritated when I was not getting some examples in the textbook I was working from. Now I know how to get them right

[mzheteo]

Hello just wanted to say thanks for this video. This helped me understand in a short amount of time and is better than my Teacher’s explanation which is very confusing. Thank you vv much!!

[gmiyadole]

The question is, how were you able to come up with the exact factors of 12 and 72 that can get us to the middle term which is -59????

[sabinamaruf]

THANK YOUUUU my math teacher isnt very helpful you saved me!!!

[animegirl]

Very good method but lacks explanation... Did you just happen to choose those numbers?

[aayushsinha]

Sir why u are not our maths teacher.I m sure that if u will be our maths teacher then we will definetly acheive full marks.And definitly this video helped me a lot.Than u very much sir.

[huanweicui]

same here whenever you factored those equations in your videos, I was like, ?? Definitely helped A LOT, thanks👍❤
