you could get oscillations or other undefined behavior if you connect multiple
regulated power supplies in parallel.

It's OK to inject power at multiple points along
the strip in my opinion, say
every 20-30' as long as they share a common ground
Only really necessary to do this if you notice dimness away from a single
injection point - there is alot of current being used along the strip between
injection points so the PSUs should not 'talk to eachother' or run any risk
of reverse current if the output voltages at the terminals are slightly off.
I've used the 5V rails from 2 different computer PSUs to run about 50m of
addressable LED strip with injection every 10m. Regular female 2.1mm barrel
jacks were soldered to one end of every strip and 2-3 male plugs w/ extension
leads were soldered to the PSUs for ease of setup/takedown.

yes it's pretty easy to solder to ends of
this LED tape
there are little copper pads and you solder to them

I mean if I cut the strip and use the power
supply that is provided then I
need to come up with another power supply for the remainder of the tape
that I want to use later. So wondering if it’s easy to solder the wires
from another power supply onto the section that has been cut off?

https://sudoroom.org/lists/listinfo/sudo-discuss i don't understand the question. There are
solder points at both ends of
each
discrete 3-LED circuit. You can splice this tape back together after
cutting
it if you solder carefully.
if you want to use multiple power supplies, they should be connected to
separate sections of LED tape, power supplies' outputs should not be
paralleled
together.
