Distribute (3a+4) through the (2a-1):


Other tutors have chastised me for not mentioning F.O.I.L. (on a different website), so here it is: F.O.I.L. stands for First, Outer, Inner, Last and is supposed to help you remember the terms to multiply when multiplying two binomials:

I am NOT a big fan of memorization tricks and so I don't find F.O.I.L. to be valuable. For example, when it comes to trinomials, F.O.I.L. does not have any value. As an alternative, I just think "every term in one polynomial needs to be multiplied by every term in the other," and that works for all cases.

A 3rd method is to use a temporary variable (I let K=3a+4 then distribute K then substitute back in for K:
