# Help with maths question? Watch

1. I've been set some work over the summer to prepare me for A level maths. How would i go about factorising questions like:
6x^3−26x^2+8x
Or if anyone has a link to video which might be helpful, since i can't find any.
Thanks
2. You can factor an from your equation, unless you forgot a term.

what i think might be the solution:

2x(3x-1)(x-4)

what I did was take out the common factors first, to get something that resembles a quadratic since that is what we learned to factorise up to in GCSE.
from there you can factorise the quadratic like you normally would

steps:
Spoiler:

6x^3 - 26x^2 + 8x

you can see that 2x is a common factor for all of the terms so factor this out.

2x(3x^2 - 13x + 4)

then factorise the bracket containing the quadratic. (I'm assuming you know how to do this)

2x(3x-1)(x-4)
