## Write the polynomials in x as polynomials of ...

The problem statement

Write the following polynomials in x as polynomials of (x-3)

Solution should be somewhat analytical in its approach.
How would you do something like this? What does it mean?

You can use any example to explain it, my specific homework question isn't necessary unless you want to see it.
eg: a) x^4
b) x^2-x-4

The attempt at a solution
i am guessing it is not as simple as
x = x - 3 but some guidance would be great.

 As I see it, it means you have to represent the polynomial in the form of another variable y = x-3. For example, f(x) = x + 10 would be changed to f(y) = y+13, where y = x-3. Though this sounds too simple, somehow.
 Yes this is what i thought also, maybe I just lucked out with a really easy question ;)

Hi JoshMaths!

(try using the X2 button just above the Reply box )

Show us your answer for x2 - x - 4, just to be on the safe side.

 Got it, thanks for the tip ;) And fwi i am doing college level maths haha so algebriac manipulations aren't the pressing issue but to make you happy... "x2 - 7x + 8"
