Bhabha scattering with polarized electrons at the Z⁰ resonance has been measured with the SLD experiment at the SLAC Linear Collider. The first measurement of the left-right asymmetry in Bhabha scattering is presented, yielding the effective weak mixing angle of sin²θWᵉᶠᶠ0ex0ex=0ex0ex0.2245±0.0049±0.0010. The effective electron couplings to the Z⁰ are extracted from a combined analysis of polarized Bhabha scattering and the left-right asymmetry previously published: υₑ0ex0ex=0ex0ex-0.0414±0.0020 and aₑ0ex0ex=0ex0ex-0.4977±0.0045.
