Four sliding tabs along the back edge of the MacBook firmly secure the lower case. Separating these tabs requires a lot of force—consider using gloves to protect your hands from the sharp edges of the lower case.
Keep the lower case flat to the frame and firmly slide it straight away from the back edge, one corner at a time, to disengage the sliding tabs.
Don't pull up until the cover is completely separated.

Remove the lower case.
During reassembly:
Set the lower case in place and align the sliding tabs with the screw heads they slide over. Press down and slide the lower case toward the back edge to engage the tabs—it'll stop sliding as the tabs engage.
When one side is engaged, it may push the other out of alignment. Check both sides as you push, there should be no gap along the back edge.
Once the lower case is flush with the frame, press down firmly along the perimeter to engage the six snapping clips.
You'll hear and feel a distinct click as each clip snaps into place.
