i swear you are the BEST youtube channel to exist i can't thank you enough thank you so much for making these videos

[@rKaraa]

HI SIR IN 11:58 WHY DID YOU NOT ADD THE DENOMINATOR FOR THE OTHER ALGEBRAIC FRACTION??

[@injwction]

with fractions you're only supposed to add the numerator, they have the same denominator so ur not meant to add the denominator like if u were asked 3/12 + 6/12 you wouldnt get 9/24 you'd get 9/12

[@rKaraa]

ohhhhhhhhhhhhh ok thank you so much @@injwction

[@someoneonthesameplanetasuu4363]

you make it seem way easier than it is. i am hoping this question will pop up in my igcses i feel like it would be worth some good marks plus it is so fun to do. tysm for ur vids :)

That’s my absolute pleasure! Hope it’s a good thing that I make it seem easier 😁🤞🏼 so glad you are enjoying the videos!

[@Clara-jc1ku]

Hello! Thanks for the video! Hum.,,, I guess there is a mistake? Around 16:44, I got p=3, q=101 and r=4. Am I wrong? I checked it couple of times... Would you mind checking it for me?

[@Dan-sz7qn]

just in case you still need help on this, adding 1/(x+2) to 1/(x-3) would form (2x-1)/(x²-x-6), which is equal to 4, multiply the discriminant with 4 and group the like terms tgt would get you 4x²-6x-23=0, now apply the quadratic formula and you'll see, hope this helps!

[@t.p_yourhouse]

A year too late but Ur right lol it simplifies

[@westy.4217]

i was confused too

[@AlphaSigmaOhioTown]

Its correct, [6 ± (4^½) × (101^½)] / 4 = [3 ± (101^½) ] / 4 If you have done completing the square, you should get this as your final answer, its just a simplified version of his answer

[@memetris6971]

At 10:25 wouldn’t u put 4 into the x values

[@TheGCSEMathsTutor]

Memetris it doesn’t say f(4) is says when f(x)=4 which is asking which value of x gives you the answer 4 😁🙏🏼

[@ahyankhan9860]

i have a question, at 8:49 why did we write the x values as 5,1 and not -5, -1

[@not...not...no.643]

Hi! 😄 basically when you have come to that final stage in solving a quadratic (when you've got two brackets) you have to reverse the sign of both of them to get x [ if u want to know exactly why, this is because the whole quadratic equals 0, so they have to cancel out if that makes sense? so instead of -5, x is actually 5 because -5+5=0. u don't need to know this, just to help u understand if it helps 😅]

Nailed all of them but I had seen some of them before. I didn't even realise the simultaneous equation one was a simultaneous equation until I had done the 2nd part. Then it all made sense. Sometimes you just have to plough in and start doing algebra and sometimes it just resolves before your mildly surprised eyes.
