If you have a question like
Find the remainder of
when the polynomial is divided by the factor x-1
so values of x=1
so the answer is -5,
my question is, if the factor x-1 is in a bracket does it change the sign?
so would x= 1? or -1? if the factor was written as (x-1)?
thanks because there was a question on a test and it gave three polynomials and three factors and you had to match them so there was a remainder of 0, and I tried both ways +/- and it only worked as if there where no brackets so your answer makes sense. I just wanted to clarify for piece of mind.
