]]>Don't you think it should be in *Help Me*.

Welcome to the forum.

Start by writing

where Q is the quotient and R the remainder, both functions of x.

R must be a linear function (ax + b) because if it had higher power of x, you would be able to further divide it by x^2 -1

If you put x=1 you will get one equation with a and b; and putting x = -1 will give another. Together you can solve for a and b.

Hope that helps,

Bob

]]>The remainder when x^45 is divided by x^2 - 1 is :-

a)2x

b)-x

c)0

d)x

e)None of these

Try to answer and it would be good if you show the method.
