How do I factorise x^3 - 4x^2 + 3x?

Just a little stuck on some maths prep.

Really grateful If anyone could help.

I don't think you can d: you would need to find a way change the middle one so it adds up to the one on the right i.e

X^3+4X^2+2X =

X^3+2X^2+2X^2+2x =

( X^3+2X^2)+(2X^2+2x) =

X^2(X+2) + 2X(X+2) =

(X^2+2X) (X+2)
