    Factoring Trinomials

    A quick review question about factoring trinomials.

    I know there are two trinomials:

    (1) One where the coefficient of x^2 = 1

    (2) One where the coefficient of x^2 > 1

    I am more concerned about the second one (where the coefficient of x^2 > 1).

    MY QUESTION:

    Can I use the Grouping Method to factor trinomials whose x^2 coefficient is > 1?

    Sample:

    3x^2 - 5 x - 2...Can I factor this guy using the Grouping Method?

    = 3x^2 - 6x + x - 2 = 3x(x - 2) + 1(x - 2) = (x - 2)(3x + 1)
