Thank you so much Sir🙏🏻. Your channel is heavenly sent. For longest time I taught I was dumb kanti no I needed a great teacher like you.

[GibsonMogale]

👏👏this topic was giving me a headache but then I've seen the light💡💡 now
🤝🤝

[kamogelomodjadji]

Your lessons are a true blessing sir🖤💯

[d.onnell_]

The greatest teacher of all time, thank you Sir!!!

[mositoboitshoko]

I'm improving ever since I started to watch this videos.. Thanks Sir

[nobuhlengcobo]

Not me understanding how to factorise a cubic function ngo last minute you so much 🙏

[callumlawson-smith]

Thank you sir, I'm feeling confident in maths for the first time in about 4 years

[tshepangsherlock]

Thank You once Again🙏🏽🙏🏽😃😊.

I'm writing Friday Paper 1, I'm not fully ready just need few touch ups then I'll be Ready😃.

Quick question, how do I show that the graph has only one point stated in the question?

Here's a scenario :
F(x) = -X³-X²+X+10 and I'm asked to show that (2;0) is the only x-intercept of F.

Thank You in advance 🙏🏽🙏🏽🙏🏽

Thank you so much sir. I do struggle with math but your videos have helped me a lot. Will it be possible for you to do past papers on calculus. Specifically Eastern Cape past papers as my teacher takes similar questions to that.

qyestion 1 a) shouldn't we take the 12 and 4a over (12+4a+b=0) to make it b=- 12-4a? i saw you just write it so which means b would be -b

[cassiusmbhalati]

21:48 Tshego's methods is similar but i use kx then when looking for k.i say k=ax+b where a stands for the well a the x the factor then b well it stands fot b .(i hope you understand sir) so it will be k=ax+b then k=(1)(2)+(-3) then k=-1 😹😹

[PrinciaBebo]

Sir by 21:14 you can also use synthetic division

[kholisantsobothi]

Thank you even though i am scared of friday papper 😓

[cassiusmbhalati]

8:26, ,on equation 2 we can make b subject of the formula then we will get b= -4a-12 then afterwards we say b=b then -2a-6=-4a-12 the solve for a the afterwards we take the value of a and sub it into the first formal then get b=0.

I'm grateful sir, If the first derivative of a cubic function is a parabola, would I be wrong If i sketched the graph on the same set of axis, the applied your strategy?

[ThokozaniButhelezi-mz]

Sir is the any alternative method that can be used to answer question c)

[tumimonare]

sir with the last question, was the calculation necessary because you can honestly read it of the graph

[lulamalurh]

wena sir uwu-best yaz kodwa😘😅....sir sokwenzan if kthiwa sinikwe ama x-int kodwa awawona ama TP i method izohluka?

[shamie.m]

for the first question can we use the Y=(x-x²)(x-x¹)²

[musamosa]

Thank you sir, can you please do probability
