## Video transcript

right a polynomial to express the total value of P $20 bills P$20 bills Q $10 bills and our$5 bills so what's the value of P $20 bills well if I have P$20 bills the value of each of those dollar bills is going to be $20 so the value of all P of them is going to be 20 P 20 P right if I have one dollar bill one$20 bill it's $20 if I have three$20 bills if P is three it's going to be $60 actually let me do that in the same colors i underlined it I underlined it in yellow so let me do the P$20 bills so 20 P is the P $20 bills then you have your Q$10 bills so plus so what's the value of those well it's going to be 10 Q if I have one ten dollar bills for $10 if I have ten$10 bills if Q is 10 is going to be worth 10 times 10 \$100 and then finally you have your are five dollar bills which are going to be worth five R dollars one five dollar bill worth five dollars to five dollar bills worth ten dollars and we're done we've expressed it as a polynomial polynomial just means that we have multiple terms here and this is three terms we could even call it a trinomial polynomial is a more general term for more than one term
