Measure and mark a line 5/16 inch from the edge of the laminate floor where it ends at the carpeted floor.
Cut a piece of end cap or carpet reducer track to fit the measured line, using a hack saw and taking care to wear eye protection while cutting.
Align the end cap track with the mark on the floor, making sure to leave ¼ inch expansion space between the end cap and the edge of laminate.
Install the carpet reducer track, using the screws provided to screw it into the subfloor with the edge facing the laminate on the expansion line.
Snap the end cap into place by gently pushing the right edge into the track and pressing along the length of end cap until it is secured by the track. The longer lip will slope to the carpet, giving your laminate floor a smooth transition into the carpeted area.
