The polynomial
has a remainder of 2 when divided by
and a remainder of 3, when divided by
. The remainder when
is divided by
is
, i.e.
can be written as
Find a and b.
Well I got this already a= 1 and b=1
but the second question I don't know what to do...
Given that
is a cubic polynomial with coefficient of
being 1, and −1 is a solution of the equation
, find
.
I'm not too sure how to start... If -1 is a solution of the question when
that means
must be a factor right? I don't know what to do from here...
