Hint: 1st factor 3x^2 - xy - 2y^2Could someone please explain how to factor the expression 3x^2 - xy - 2y^2 + 3x + 2y by using the grouping method?
Knowing what the answer is, I can rationalize a way, but other than that it is a pick, choose, and try. Remember, when using grouping, you sometimes have to add things in and then subtract them out for use in a different place (or subtract, then add).Could someone please explain how to factor the expression 3x^2 - xy - 2y^2 + 3x + 2y by using the grouping method?
