Trinomial Factorisation grade 10: Number in front not a 1

Factorisation of trinomials with a number in front of the x^2 which is not equal to 1 can be more challenging. In this lesson we learn how to do it.

You people need to stop shoving your religions down our throats, everywhere I go I see bullpoop like this

[@user-wp3te1uj7t]

this is a great method that i will keep in mind but holy sh3t its ineffective when the number is large like 36 or 64

I think lm just stupid, cause l still don't understand. Hai God what is wrong me me😭

So Kevin, what if the last number is a big number like 36 or 48

[@viktorcalebmon9823]

U need to find a way to get the number in the middle not including the varible, im grade 5 but know this, im 5 years advance from my school years in math😂😂😂😂😂🎉🎉🎉🎉🎉

[@tiisetsow.3474]

Had to come back and learn basics for final exams bcos I didn't learn it last term 😢😂

[@user-fu4em5ck1b]

Hmm hi Kevin I tried your method with this expression 2x^2-5x-12 they factorised it and got (x-4)(2x+3) I don’t understand how they got it

[@user-oc8zn2qo9q]

Most of the time to check if the ans is correct which it is u must multiple each bracket mean x time 2x is 2x^ X time 3 is 3x And on and on sorry for not finishing data is running low but 👍

[@user-uy9ne5op6q]

thank you so much for this video but here is a thing after getting out final answer , why can't l get the same question when i multiply it back .

[@HulisaniThendo-dz9vv]

Pro tip , Both brackets will have the same sign as the middle term if the trinomial ends with a positive sign , e,g x - 6x + 8 . This ends with positive 8 meaning both brackets will have a minus in the middle as the middle term is -6x 👍

[@lwandle3787]

here are the formulae for you to know whether what sign must be in the two brackets +++=++ positive in the first number second and third equals to positive on both brackets same for these + - += - - + + - =biggest factor gets + + - - = biggest factor gets -

[@Oxford-da-soul_official]

should we make table exactly like yours our it doesn't matter ??

is a Trinomial a 3 faktoor

[@cleocarwoolar3488]

if you are familiar with the AC method can you please explain why it would not work?

[@chocolateangel8743]

You could use it. It's just a different way of doing it. The only down side to using an version of the AC method is that AC could become quite large, depending on the numbers in the problem. Once you get good at the method in the video, it can be really fast -- but it does take a lot of practice.

[@neurogirly-wn7ru]

Just multiply the first and last term

[@ffhjnbvbkkbb4285]

really

[@reanisher3604]

7:13 but isn't a negative plus a negative a positive? It's not that I'm questioning I'm just a bit confused 😕

[@user-yv5sj4rn6n]

It's not necessary

[@HulisaniThendo-dz9vv]

Always remember that the bracket will always have opposite signs if the trinomial ends with a negative sign e.g 2x + x -6 . This ends with minus 6 so the two brackets will have opposite values . The biggest value of your brackets will take the sign of the middle term of your trinomial 👊 Good luck on your papers guys . God is always with all of us 🤜🤛

[@mlungisimkhize9406]

Can i factorise it using other numbers in the "cross"?

[@amandamantlane2675]

Check out how to factorise trinomials by the organic chemist or

[@chocolateangel8743]

Yes. He used the numbers he did because of the numbers in the original problem. If you do a different problem, the numbers you put in the cross are going to be different.

[@bongekilenasha237]

I am scared of what I will write tomorrow 😢

[@jshakekurumpo8989]

Another method is using the PAF (Product Addition Factors) 2x² - 7x - 4 the product is 2 x 4 = 8 Addition is the number in the middle -7 Factor is ho we get to the addition number -8 + 1 if you put that all together its (2x² - 8x) (1x - 4) and the rest is the same in the video Hope I helped someone understand it

You should start doing grade 1 1

[@b1g14]

don''t know how to thank uuuu

[@viktorcalebmon9823]

Im 5th grade and will teach you a trick: 1 -4 X 2 1 This means cross multiply, you need to get the number in the middle that is "-7" Add after like this, " -8 + 1 = -7 Thats it, your welcome.😅😅😅😅❤❤❤❤🎉🎉🎉

[@Patwal77]

Why cant we just fimd factors of 8 (2x4)

[@Ntombi_Majara]

I tried it before it didn't work 😭😭😭😭

[@wavyXRL]

Because kevin didnt say so bozo

[@TienShan3.14]

Yes, that works when the first and last coefficients are small, like this example. You would be looking for factors of -8, which is -8 and 1. The problem that approach is when the product of those terms are large. Try his method to factor 132x^2 -199x +60, you can find the numbers -144 and -55 quicker than find them in the factors of 7920.
