We present a measurement of the form-factor ratios rV=V\(0\)/A1\(0\) and r2=A2\(0\)/A1\(0\) for the decay D+→K_*0e+ve. The measurement is based on a signal of approximately 3000 D+→K_*0e+ve, K_*0→K-π+ decays reconstructed in data from charm hadroproduction experiment E791 at Fermilab. The results are rV=1.84+/-0.11+/-0.08 and r2=0.71+/-0.08+/-0.09.
