In the contribution, a linear differential system with a single delay $$ \frac{dx(t)}{dt} =A_{0} x(t)+A_{1} x(t-\tau)+bu(t), t\ge t_{0} $$ where $A_{0}$, $A_{1}$ are $n\times n$ constant matrices, $x\in R^{n}$, $b\in R^{n}$, $\tau>0$, $t_0\in{\mathbb{R}}$, $u\in R$, is considered. A problem of minimizing (by a suitable control function $u(t)$) a functional \begin{multline*} I=\int _{t_0}^{\infty }(x^{T}(t)C_{11}x(t)+x^{T}(t)C_{12} x(t-\tau) \\ +x^{T}(t-\tau)C_{21}x(t)+x^{T}(t-\tau)C_{22}x(t-\tau)+du^{2}(t))\mathrm{d}t, \end{multline*} where $C_{11}$, $C_{12}$, $C_{21}$, $C_{22}$ are $n\times n$ constant matrices, $d>0$, and the integrand is a positive-definite quadratic form, is considered. To solve the problem, Malkin's approach and Lyapunov's second method are utilized
