The Factor Theorem

In this video I explain the factor theorem and how it can be used to factorise polynomials and solve equations. This video is intended for those studying AQA's Level 2 Further Maths GCSE.

I knew because I designed the question. I am just using it to demonstrate the theorem. In the exam they will not expect you to work out the factors without giving you one first.

I very much appreciate that you took the time to explain everything including what factors even are and not taking any knowledge for granted, this allowed me to fully understand the topic

This channel is better than my actual teachers.

Thank you for running through this - you are really clear at explaining it :)

[joeyramstad]

thank you so much for this! reviewing my pre-calc in preparation for university calculus after a five year gap and this was for some reason one of the hardest concepts for me to remember. my textbooks and other online resources just couldn't explain in a way that made sense to me. This video helped recover faith that I'll be able to do this!

Why is this channel underrated.
Thanks man

at 5:40 how do you know so surely that 3 in a factor is there a method to work it out in the exam

When the coefficient of x in the factor is 2(or anything not 1), why do you make it equal to 0? Like when you have 2x+1 you figure out if 2x+1=0 then x=-1/2 and then you substitute the x into the equation instead of a… how does this work

[kebabz]

imo the grid method that tlmaths taught for factorising is way easier but still great vid as always

at 6:50 you say 4x^2 - 3x^2= 7x^2... is that correct?
