I assume you want to factor this:


3x^2 - 6x


Do you notice that there are factors that divide evenly into both 3x^2 and 6x? If you divide 3x^2 -6x by that common factor, what are you left with?

Perhaps an example would help: consider how to factor 8x^3 + 6x^2. First notice that the '8' and the '6' have a common factor of 2, and the x^3 and x^2 terms have a common factor of x^2. Consequently you can divide through by 2x^2 to get:


2x^2(4x+3)


To check that this is correct try multiplying it out and see if you get the original equation back again:


2x^2(4x+3) = 2x^2 \times 4x + 2x^2 \times 3 = 2x^3 + 6x^2


Now try his process with your problem. Post back with your answer and we'll check it for you.
