In this talk I will discuss the results of the full shape analysis of two-point clustering measurements from BOSS galaxy sample combined with the quasar sample from eBOSS, analysed using an updated recipe for the non-linear matter power spectrum and the non-local bias parameters. I will focus on the cosmological parameters that are not defined through Hubble parameter, h, and highlight how this parameter space not only allows us to appropriately and accurately compare constraints from different probes when assessing consistency, but also enables tight constraints in the extended cosmologies with free dark energy equation of state parameter w. I will present the resulting constraints in LCDM cosmologies, as well as a number of extended models where w is allowed to vary freely and show how clustering can be complimented by external probes, namely, CMB (Planck) and weak lensing (3x2pt measurements from DES Y1).
