Best ResponseYou've already chosen the best response.0okay so we multiply everything by the 1, yes?

Best ResponseYou've already chosen the best response.0why is it just 1 rather than x  1?

hba

Best ResponseYou've already chosen the best response.1dw:1353960062608:dw We add p and q so we get p+q now and then multiply it by 1

Best ResponseYou've already chosen the best response.1In this method we take x1 put it equal to 0 so x1=0 x=1 So we have to put this .

Best ResponseYou've already chosen the best response.0is it usually the opposite? so instead of 1 it is 1?

kerribaberri

Best ResponseYou've already chosen the best response.0so if i was to be given x  3, it would be divided all by 3?

Best ResponseYou've already chosen the best response.1dw:1353960245291:dw here we have added (p+q)+(1)=p+q1 and then multiply it by 1

Best ResponseYou've already chosen the best response.1@kerribaberri Yeah you are right but if the question come 2x2=0 then 2x=2 x=1

Best ResponseYou've already chosen the best response.1Did you get my step above ?

kerribaberri

Best ResponseYou've already chosen the best response.0then the last step after that would be (p + k  1 + 3) ?

Best ResponseYou've already chosen the best response.0i was wondering why there was a line in between

hba

Best ResponseYou've already chosen the best response.1dw:1353960695933:dw Here P(x)=polynomial of x and R(x)=remainder of x So we seprate them ,Got it @kerribaberri ?

Best ResponseYou've already chosen the best response.1We have been provided in the question that the remainder is 4 so R(x)=4 got it ?

kerribaberri

Best ResponseYou've already chosen the best response.0yeah, i got it. :)

hba

Best ResponseYou've already chosen the best response.1I can replace R(x) with p+k1+3 so p+k+2=4 got it @kerribaberri ?

Best ResponseYou've already chosen the best response.1The 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 ?

Best ResponseYou've already chosen the best response.1The method is bring the k down multiply i by 2 so it will become 2k then it will go under p
