Aircraft originally put on a vector. Needed to widen out his downwind for a turn onto final. I planned to only have him on a vector for 1-2 miles.  I got busy; requested a Radar Assist or to split  the sector.   Didn't realize he was in a 6;000 foot Minimum Vectoring Altitude but noticed him very close to my 9;900 foot Minimum Vectoring Altitude. As the pilot was reading back his clearance I turned the aircraft towards the final approach course and lower terrain immediately after noticing.
SCT TRACON Controller reported they left an aircraft on a heading longer than they planned and the aircraft flew below the Minimum Vectoring Altitude.
