Hey im trying to study for my EOCTs(End of course tests) and i want to make sure that i get the easy stuff before studing the harder stuff. so my question that i have is simple but i think i need help with it, not cause im stupid but because i want to make sure im studying the right stuff.

here is the question: Multiply (4x + 1)(4x - 3)

so i think to solve this problem i need to use the foil method. wich is first inner outher last.

so here are my steps shown.

1. First- (4x X 4x)=16x squared

2. outer-(4x X -3)= - 12x

3.inner- (1 X 4x)= 4x

4. last- (1 X -3) = -3

after this step i think i am lost. can i please have help to answer the rest of the problem step by step. all help would be very appreatiated.
