    What did you try?

    An example is : 3x^2 + 6xy , when factored gives 3x(x+2y)

    You 'move' the common factors out and insert brackets.

    Pull out all of the a's you can, then the b's and then look for a common factor among the constant numbers and pull that out. If you can, factor what's left...
