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.
