This may sound simple (and I guess it is), but what is the technique employed to factor the expression below? Also, are there good resources online that you would know where one could practice it?
$$2x^2 +7xy + 3y^2$$
Thank you.

Quadratics of the form $ax^2+bx+c$ can be factored using the "ac method". The product of $a$ and $c$ is factored and the factors are summed to get $b$.
In your case:
$2x^2+7xy+3y^2=2x^2+xy+6xy+3y^2=(2x+y)(x+3y)$
