x-2=0
x=2


According to remainder theorem,if p(x) is divided by x-2 the remaimder will be p(2).


p(2)=2(2)^3+13(2)^2+2-70
p(2)=16+52+2-70
p(2)=70-70
p(2)=0


Hence,remainder =0;x-2 factor of the above polynomial.

arc555: but where is the que.
DhruvAsopa: what is the meaning of que.
arc555: you havd to show that remainder=0 in both the cases
DhruvAsopa: no there is not in question
arc555: do you know about factor therom
DhruvAsopa: yes P(x)=G(x)×Q(x)+R(x)
arc555: yaa
DhruvAsopa: so please find the answer
arc555: but when r(x)=0 then the G(x) wiil be the factor of p(x)
DhruvAsopa: I not understand what you are saying
