How do I Multiply, simplify, and write in descending order:

%28t+%2B+4%29%28t%2B1%29%282t-2%29


Step 1. Let's start with multiplying (t+4)(t+1) using the FOIL method: 1) Multiply the F-IRST Terms t*t, 2) Multiply the O-UTER terms t*1 3) Multiply the I-NNER terms 4*t and finally 4) Multiply the L-AST terms, 4*1 or

%28t%2B4%29%28t%2B1%29=t%2At%2Bt%2A1%2B4%2At%2B4%2A1=t%5E2%2Bt%2B4t%2B4=t%5E2%2B5t%2B4

Step 2. Next we'll take the result of Sttep 1 given as t%5E2%2B5t%2B4 and multiply %282t-2%29. Take each term in t%5E2%2B5t%2B4 and multiply by 2t-2. Then simplify by adding like terms



Note: What we did here is similar to the steps in Step 1.

Step 3. ANSWER

%28t+%2B+4%29%28t+%2B+1%29%282t+-2%29=2t%5E3%2B8t%5E2-2t-8

I hope the above steps were helpful.
