I'm not too good at algebra and need help with getting something into the appropriate form. If I have something like:

$\displaystyle (2k_1 + 1) + (2k_2 + 1)$ What would be the appropriate form?

I have an example of the following, but I'm not sure how to apply it to the above equation (in other words, how to handle the extra +1):

$\displaystyle (2k_1 + 1) + 2k_2 = 2(k_1 + k_2) + 1$
