which technique would be the best applied to factor the polynomial

We are given the following polynomial:
[tex]2x^2+xy+6x+3y[/tex]To factor the expression we can associate terms like this:
[tex](2x^2+xy)+(6x+3y)[/tex]That way, we can take common factors on both parentheses:
[tex]x(2x+y)+3(2x+y)[/tex]And then again take a common factor "2x + y":
[tex](2x+y)(x+3)[/tex]This means that the best technique to factor in is grouping.
