|dw:1353959611123:dw| got this part ?
Lets do this fast @kerribaberri Just tell me if you do not understand.
alright, is there another way to do this though rather than to divide all the time?
an easier solution or something?
@kerribaberri This is the easiest method on earth if you learn it The easiest and the fastest :)
alright! let's do this LOL
|dw:1353959860849:dw| We take the k down.
|dw:1353959905760:dw| We multiply the k by 1 k*1=k
|dw:1353959933565:dw| We multiply it and put it there,following me @kerribaberri
okay so we multiply everything by the 1, yes?
why is it just 1 rather than x - 1?
|dw:1353960062608:dw| We add p and q so we get p+q now and then multiply it by 1
In this method we take x-1 put it equal to 0 so x-1=0 x=1 So we have to put this .
Did you get my step above shown in the diag ?
yes, i did.
is it usually the opposite? so instead of -1 it is 1?
so if i was to be given x - 3, it would be divided all by 3?
|dw:1353960245291:dw| here we have added (p+q)+(-1)=p+q-1 and then multiply it by 1
@kerribaberri Yeah you are right but if the question come 2x-2=0 then 2x=2 x=1
Did you get my step above ?
ahh, i see okay
then the last step after that would be (p + k - 1 + 3) ?
|dw:1353960431384:dw| Yeah right :D Shall i continue ?
|dw:1353960534857:dw| We will always seprate the last number :)
I know you will ask why ? right ?
yeah, why? :P
i was wondering why there was a line in between
|dw:1353960695933:dw| Here P(x)=polynomial of x and R(x)=remainder of x So we seprate them ,Got it @kerribaberri ?
ohhh okay i get it @hba
We have been provided in the question that the remainder is 4 so R(x)=4 got it ?
yeah, i got it. :)
I can replace R(x) with p+k-1+3 so p+k+2=4 got it @kerribaberri ?
so p+k=4-2 p+k=2
Now lets solve the other one.|dw:1353961284346:dw| Your turn @kerribaberri Do it i'll help you where you go wrong :)
so 2 goes on the left..
Yeah start doing it in the diag
k p -2 2 ? o_O
Do it in the diag lol
LOL did i pick the correct numbers though?
Where did -2 and +2 come from ?
i took the 2 from the equation and.. ohhhhhhh am i supposed to multiply -2 by 3?
ohhhh wait, i didn't realize the 3 and the 2 were exponents..
i thought they were base numbers
The equation in the first thing was kx3 + px2 - x + 3 so i got k p -1 3 In the second case the equation iss kx^3+px^2 so you should get k p right ?
Got it ?
@kerribaberri Please concentrate Its easy.
okay i got it..
i see where the k and p are coming from but i don't see where the last two come from
|dw:1353962174399:dw| Now continue
Got where the last two came from ?
yeah i see it there because there are numbers, but this one has none?
So you do not have to write anything.
ohhh, i never thought that was an option
Are you solving it now lol ?
r(x) = 21
@kerribaberri Please try.
@kerribaberri First solve it lol
|dw:1353962559852:dw| bring the k down multiply it by 2
if there's no numbers|dw:1353962609644:dw|
What is wrong with you ?
The method is bring the k down multiply i by 2 so it will become 2k then it will go under p
@kerribaberri Please try to understand i feel like slamming my head in the wall.
@kerribaberri You there ?
i'll just ask someone else LOL
No i am showing you wait.
No you are not..
So, R(x)=21 2x+p=21 got it ?
@kerribaberri got it ?
