let 's do another synthetic division example . and in another video , we actually have the why this works relative to algebraic long division . but here it 's going to be another just , let 's go through the process of it just so that you get comfortable with it . and now is a good chance to give it a shot , to actuall...
i just have a positive 7 . and now let me just draw my little funky synthetic division operator-looking symbol . and remember , the type of synthetic division we 're doing , it only applies when we are dividing by an x plus or minus something .
and also , where did the `` operation '' symbol come from ?

and now we 're ready to perform our synthetic division . so we 'll bring down this 2 and then multiply the 2 times the 3 . 2 time 3 gives us 6 . 0 plus 6 is 6 .
the denominator is 3x-2 would i still put positive 2 at the same place where sal puts the 3 0 in the video or does the 3x affect this ?

and then i have a positive 3 times x squared . negative 2 times x . and then i have a constant term , or zero degree term , of 7 .
the x^5 term was 2 , and the x^4 term was 0 ( which became 6 ) , so how did two become the x^4 and 6 the x^3 ?

multiply that times 3 . the numbers are getting kind of large now . so that 's going to be what ?
i mean why ca n't we just use the number beside the x and then subtract the numbers on the second row from the numbers on the first row instead of add the two rows numbers altogether ?

so it 's really 0x to the fourth . so i 'll put a 0 as the coefficient for the x to the fourth term . and then i have a negative 1 times x to the third .
sal says that the coefficient to the x^4 term is 0 , would n't it be actually 1 ?

and you add 480 to 7 , and you get 487 . and you can think of it , i only have one term or one number to the left-hand side of this bar here . or i 'm just doing the standard , traditional x plus or minus something version of synthetic division , i should say .
so the last term is always the remainder ( if we have one ) right ?

so it 's really 0x to the fourth . so i 'll put a 0 as the coefficient for the x to the fourth term . and then i have a negative 1 times x to the third .
how do you know whether you put an addition or subtraction sign into your solution ?

negative 2 times x . and then i have a constant term , or zero degree term , of 7 . i just have a positive 7 .
is there any way that there would n't be a remainder unless the constant was zero ?

and the process we show -- there 's other ways of doing it -- is you take the negative of this . so the negative of negative 3 is positive 3 . and now we 're ready to perform our synthetic division .
why is the 3 on the outside positive suddenly ?

but then we have our final answer . it 's going to be -- and let me work backwards . so i 'll start with our remainder . so our remainder is 487 . and it 's going to be 487 over x minus 3 .
if the remainder is not zero , should i just keep going with the same number i 've been using to synthetically divide ?

and you add 480 to 7 , and you get 487 . and you can think of it , i only have one term or one number to the left-hand side of this bar here . or i 'm just doing the standard , traditional x plus or minus something version of synthetic division , i should say .

and remember , the type of synthetic division we 're doing , it only applies when we are dividing by an x plus or minus something . there 's a slightly different process you would have to do if it was 3x or if was negative 1x or if it was 5x squared . this only works when we have x plus or minus something .
just wondering , would this be considered an easier way to divide polynomials ?

and then finally , 160 times 3 is going to be 480 . and you add 480 to 7 , and you get 487 . and you can think of it , i only have one term or one number to the left-hand side of this bar here .

i think you 're starting to see how this gets pretty hairy very fast . so let 's say that bank a , one of its $ 3 billion in assets , is a loan to bank c. and so on bank c 's balance sheet , it 'll say loan from bank a . or so we owe a $ 1 billion .
does bank c still need to pay off the loan ?

maybe a billion of these are a loan from bank b . and if this is a loan from bank b , bank b would have an asset called loan to bank a . on bank b 's balance sheet we 're calling this a loan to bank a .
a then would have $ 1b cash to repay bank b , would n't it ?

when t is equal to 5730 , this exponent is going to be one , which we want it to be . we 're just gon na multiply our initial value by 1/2 once . when this exponent is two times 5730 , when t is two times 5730 , well then the exponent is going to be two , and we 're gon na multiply by 1/2 twice .

well , we know at every 5730 years , we lose exactly half of our mass of carbon-14 . every 5730 years . so let 's think about what happens when t is 5730 .

well , then , it 's gon na be this times 1/2 . so it 's gon na be 741 times 1/2 times 1/2 . so we 're gon na multiply by 1/2 again .
