Question 81362
If you can learn to be patient, someone will help you. Submitting the problem numerous times will not.

--------

5x^2 - 2xy + 5x - 2y

Let's group the terms so it will be easier for us to look at when we factor: 5x^2 + 5x - 2xy - 2y

How do we get 5x^2? It must be 5x(x).

(5x   )(x    )

How do we get -2y in two empty spaces? It must be either (-2y)(1) or (2y)(-1). In this case, it is (-2y)(1) because we have - 2xy.

(5x - 2y)(x + 1)

There you go.
