# How do you factor the expression #18r^2 + 12ry - 3xr - 2xy#?

(3r + 2y)(6r - x)

group the terms into 2 'pairs'

now factor each pair:

6r(3r + 2y) - x(3r + 2y)

There is a common factor of (3r + 2y) in each pair.

thus : (3r + 2y )(6r - x)

To factor the expression (18r^2 + 12ry - 3xr - 2xy), you can first look for common factors among the terms:

(18r^2 + 12ry - 3xr - 2xy)

(= 6r(3r + 2y) - x(3r + 2y))

Now, you can see that both terms share a common factor of ((3r + 2y)):

(= (6r - x)(3r + 2y))

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
