[@75things75]

Yknow, I've struggled with factorisation since y7 and I'm now in y9, about to take my end of year exams. It's weird how this amazing youtube channel can explain this better in 8 minutes than my school can in 3 years. Thanks for the rlly helpful videos man.

[@Aisha-gd6dq]

Thank you ! I’m revisiting all the maths topics I’ve covered so far in year 9 so I can be attentive in year 10.

[@Cloudey-puffo]

Thank you so much i was confused when learning this as i didint know wich letter to keep so when you kept the b i was complexed why you didn't keep the a instead until later you kept the x in 5x that made me realise all the units have x and in the other equation both numbers have b thank you a lot for the help you and your team included❤❤❤

[@RoyalPigeon369]

My question: 2x^2-x Answer: HCF of 2 and 1 = 1 (because they're both prime numbers) HCF of x x x + 1 x x = x x(2x-1)

[@beastslayer1559]

ty for such well put together videos very helpful n easy to understand

[@thebigbarbosa1]

Why positive 3? I have no idea where the plus comes from. please explain.

[@haliali2143]

Just ile before when you try to get what multiplies with 4x to get 8xsquared, you look fr what multiplies with 4x to make 12x . So 4x times 3 is 12x. And that's where you get the positive 3

[@Stagedreamerr]

@@haliali2143it gives 3 but why is it positive? That’s what we’re confused about

[@Nour-Talha]

because its 4 divide + 12 so you do 4 divide by 12 which is 3 then add the + and that's where you get +3

[@urf4vdivine]

some numbers are negative, which means they are below 0, like -1 -2 -3…. etc. but positive because its more than zero - ‘normal numbers’ 1, 2, 3… etc. so that is why its plus, if it was for example 4 - 8 which is -4 it would be minus. if you don’t understand i can still help :)

[@tuannurhananituanmuda1673]

what software did u use to edit your vids?

[@Az-gf6lt]

India

[@murtazakhan552]

@@Az-gf6lt lol

[@melonman2282]

He used a really complicated method finding the highest common factors, just find the highest number they share in times tables, so write down 1x(number) 2x(number) 3x(number) going on both numbers until you hit a number, or if you have a times tables sheet just check the highest number they share on there

[@jojoluvspuppies]

You can use any working method (or a method you've been taught) to find the HCF.

How did you get +3 it does not make sense

[@manschuhan1736]

Because if we multiply plus 3 and 4x we get plus 12x 😊

[@iya4631]

im so stuck someone help me, 14t+8. the HCF is 2 so 2t( ...) How do you get 2t to 14 t, you would multiply it by 2, but the answer is always 2t(7T!!!! HOW IS THE T THERE

[@floppyduck1336]

Idk if you still need help but 14t+8, you find the HCF, so 2 like you said. But because the t is not in both terms, it just stays as 2. You add the t in the brackets. So it would be 2(7t+4) Because 2×7t is 14t, then 2×4 is 8, which brings you back to the original 14t+8.

Really hope you use your brain and have a different job(not KZbin) and become a millionaire

[@ravex5169]

He can choose

[@lordxeno8270]

stupid comment

[@amoonynight]

Actually the smartest job they could do is KZbin. The money from ad revenue alone can reach $1000-10,000 per video depending on the views. Not to mention it's easier to do then an actual job and more rewarding after reaching monetization which is when you start earning money. In short, by KZbin you can be at least financially stable if not anything else.
