[@marialoveday9443]

I just watched this video for my brother's benefit but I'm yr 11 and we were looking at triple brackets and I didn't understand where all the extra terms for coming from as I was multiplying them by the first term in the bracket and then multiplying the already multiplied terms by the second term in the bracket. Thanks for clearing up my confusion!

[@Cognitoedu]

Glad our video helped it make sense 👍

Thanks a lot!!.. your explanation is quite simple and clear to understand 👍👍

hey, at 0:53 my answer is coming 2x cube + 11x square + 34x + 24. am I tripping or did you get it wrong?

[@bettyberhane3300]

I think where you got it wrong is the 7x squared + 6x + 8x squared so basically you just need to add the 7x squared +8x squared which means just add the number 8+7= 15 and then add the x squared so 7x squared + 8x squared= 15x squared. I hope you get it. Bye.

[@smarty_rev6922]

Hi on the last question i dont know how you got 2x cubed + x squared - 13x + 6 like how did you get x squared from minus 5x squared + 2x and then 13x ??? i need help on that question

[@issy.7381]

the x’s multiply with each other so for -5x squared, it’s because x has been multiplied by -5x so the x’s multiply together to make the x squared part !! (hope that makes sense)

[@tracycasey4668]

Could you do a video about iteration please ? Thank you :))

[@alweis3983]

This part is funny 4:37 haha😂

[@user-tm9os1ks3t]

Can we ignore the middle one😢

[@queens1ey]

thank u

[@xxmissy_15]

where did the 7x come from ???????!!!

[@ndanjinanyangwe1048]

I have the same question

[@Ttx1a]

hes got it by doing '4x + 3x' he just simplified it down

[@hitou682]

When you normally multiply the brackets, you will get (2x squared + 4x + 3x + 6) ans from here you add the like terms which are '4x + 3x' and thats how you get 7x.

[@ndanjinanyangwe1048]

Why are signs ignored

[@ronanmcgrath117]

can you ignore any of the first 3 brackets

[@lily-no6ss]

yes

[@willeysmit9948]

pls add this video on your website as well

[@sadiaaziz3708]

[@nasreensmith1220]

Does it matter whether which one to ignore ?

[@Cognitoedu]

Out of the three brackets? No just pick any two to multiply together first.

[@samhale6918]

This might save me tomorrow

[@Slap_Poggr]

Question.
On 1:42, why is the operation is randomized? (-,+,-)
