# 1 A PROPERTY OF POLYNOMIALS

Let $f(x)$ be a polynomial in $x$ where $x$ and the coefficients $a\in\mathbb{(}Z)$ and $bx$ is a square re $k\in\mathbb{(}Z)$ .

Proof: There is no loss of generality in taking $k=1$. By Taylor’s theorem we get

$f(x+f(x))=f(x)+f(x)f^{{\prime}}(x)+(f(x)^{2})/2f^{{\prime\prime}}(x)+(f(x)^{3}% )/3!f^{{\prime\prime\prime}}(x)....$

$=f(x)(1+f^{{\prime}}(x)+f(x)/2*f^{{\prime\prime}}(x)+f(x)^{2}/3!..)$

i.e. $f(x+f(x))$ is $\equiv 0(\mod(f(x)).$

### LaTeX in forums is allowed now

I added some LaTeX markup to your post, but I’m not entirely sure what the request is. The way you set up the question it’s not clear what role $a$, $b$, and $k$ play, for example.
