  Based on Schoenberg conjecture \textit{[Amer. Math. Monthly.,
1986]}/Malamud-Pereira theorem \textit{[J. Math. Anal. Appl, 2003]},
\textit{[Trans. Amer. Math. Soc., 2005]} we formulate the following conjecture
which we call C*-algebraic Schoenberg Conjecture.\\ \textbf{ C*-algebraic
Schoenberg Conjecture : Let $\mathcal{A}$ be a C*-algebra. Let $d\in
\mathbb{N}\setminus\{1\}$, $P(z)= (z-a_1)(z-a_2)\cdots (z-a_d)$ be a polynomial
over $\mathcal{A}$ with $a_1, a_2, \dots, a_d \in \mathcal{A} $. If $P'$ can be
written as $P'(z)= d(z-b_1)(z-b_2)\cdots (z-b_{d-1})$ on $\mathcal{A}$ with
$b_1, b_2, \dots, b_{d-1} \in \mathcal{A} $, then \begin{align*}
\sum_{k=1}^{d-1}b_kb_k^*\leq
\frac{1}{d^2}\left[\sum_{j=1}^{d}a_j\right]\left[\sum_{j=1}^{d}a_j\right]^*+
\frac{d-2}{d}\sum_{j=1}^{d}a_ja_j^* \end{align*} and \begin{align*}
\sum_{k=1}^{d-1}b_k^*b_k\leq
\frac{1}{d^2}\left[\sum_{j=1}^{d}a_j\right]^*\left[\sum_{j=1}^{d}a_j\right]+
\frac{d-2}{d}\sum_{j=1}^{d}a_j^*a_j. \end{align*}} We show that C*-algebraic
Schoenberg conjecture holds for degree 2 C*-algebraic polynomials over
C*-algebras.
