Why does substituting -b into the equation give you the remainder? I get that if dividing by a factor you should get a remainder of 0, but I don't understand why you'd substitute -b to divide by (x + b).
Hey! first of all thank you for this video. Do you know any good sides from where I can revise for my a level exams? I have to resit maths this may june and I really need help, thank you!
Well explained! Do you have a contact email? I have some topics that I have some queries on! And also any revision sources for the GCSE legacy resit this may
Maths Genie also, are there any resources on: Ration notation, including reduction to its simplest form and fraction notation. Also, calculating the area of a compound shape made from triangles and rectangles.. thanks
(x+1) is a factor so you sub in the alternate sign so in this case (-1), this applies to all questions of that sort. For example if the factor was (x+3) then we would sub in (-3) instead of the x and if factor is for example (x-3) then sub in (3). If that makes sense :)
@@vseunos9261 Thank you. My question is more is there a rule I have to follow or is if just one of those things in maths that "just is" and there is no reasoning for it?
This was so helpful.. Thank you 😊
Thanks. It helped ❤️
Thank it really help me

For a better explanation of remainder theorem I recomend this video:

as, x+b=0
=)x=-b
exactly i dont get it
MY O LEVEL MATH FINAL IS IN 30 MINUTES THANK YOU SO MUCH :D
How was it?

haha not anymore. corona hopefully you get predicted grades which will be good enough! 😃
Adam I still have to, im gonna appear in oct instead of may!
Sana - oh no that’s a shame. Anyways sure you will do well 🤞
Thor Parker I’m sorry what is CAG? And yes I had my P4 maths on 22nd oct and it went horrible. But P1 wasn’t that bad

Maths Genie thank you! You are amazing

The facta feowem😭
at 4 mins 10 seconds you say about subbing in -1, why?
(x+1) is a factor so you sub in the alternate sign so in this case (-1), this applies to all questions of that sort. For example if the factor was (x+3) then we would sub in (-3) instead of the x and if factor is for example (x-3) then sub in (3). If that makes sense :)

@@OptimusXZero bit late but I think it's because x+1=0 so when you subtract 1 from both sides (or swap the 1) it becomes x=-1
why do you have to do that tho
(Math genie 🧞♂️) 🤣🤣🤣🤣🤣
ur British luv
