  The study conducted in this research paper utilizes the $f(Q,T)$ gravity,
where $Q$ represents non-metricity and $T$ represents the trace of the
energy-momentum tensor, to investigate the accelerated expansion of the
universe. To complete the study, an effective EoS with one parameter $\alpha$,
is parameterized as $\omega _{eff}=-\frac{3}{\alpha (1+z)^{3}+3}$. The linear
version of $f(Q,T)=-Q+\sigma T$ is also considered, where $\sigma$ is a
constant. By constraining the model with six BAO points, 57 Hubble points, and
1048 Pantheon sample datasets, the parameters $\alpha$ and $\sigma$ are
determined to best match the data. The cosmological parameters and energy
conditions for the model are derived and examined. The results show that the
model is in good agreement with observations, and can serve as a valuable
starting point for analyzing FLRW models in the $f(Q,T)$ theory of gravity.
