Divide the following polynomial using synthetic division, then place the answer in the proper location on the grid. Write answer in descending powers of x. (x^3 -4x^2 +4x-1)÷(x-1)
Do you know how to do synthetic division?
not really
https://youtu.be/1byR9UEQJN0 you can watch this video that explains it well, or would you like me to try to explain it?
honestly id rather you try to explainit
Okay so first you need to know what the set-up looks like, it's different than normal long division.
|dw:1466537213682:dw|
So to start, what are you dividing by?
x-1
Yup. So when you solve that, what is x equal to?
x-1=0
1
Ok good. Always remember that when you plug that number in, you have to set the equation equal to 0 first. So then you can plug 1 in |dw:1466537403416:dw|
?
Then take ur polynomial and using the numbers in front of each variable write them along the top (without the x's)
1,4,4?
Yeah, but don't forget the negative in front of that 4 and you also use the constant at the end. So when you write it all in it should look like: |dw:1466537622172:dw|
Does tht make sense so far?
yea
Okay cool. So that's how you set it up. Then you're gonna drop the first number down.|dw:1466537777666:dw|
