The analysis of 82386 selected K μ3 decays has been performed. Two solutions both for the vector and scalar formfactors have been obtained, and for each solution the validity of linear approximation is shown. One of the solutions which agrees with the μ-e universality hypothesis, gives the following values for the linear expansion parameters: λ + = 0.046 ± 0.008, λ O = 0.024 ± 0.011.
