I am trying to work at home.

On my work computer, I have 2 monitors, set to "extend" these displays.

On my Windows 10 Pro laptop at home, I have the two monitors (the laptop screen), and an external Dell 24" monitor connected via HDMI.  These 2 monitors are set to "extend" these displays.

On my laptop, I remote (using Remote Desktop Connection) into my computer at work with the setting in Options \ Display tab set to "use all my monitors for the remote session".

I would think whatever appears on the left monitor (at work), would appear on the left monitor (which is my laptop screen at home), and whatever appears on the right monitor (at work), would appear on the rightt Dell monitor (at home).

Am I missing something here, because this is not working as I thought it should work?

Can i extend the RDP screen to use up both monitors at home?

Yes, you should be able to use two monitors at home for your RDP session.

rdp connects you into the system. It does not translate the monitors that are physically connect through RDP

To have your session span multiple monitors, your RDP connection should specify the span
Mstsc /public /w:3840 /h:1080 /v:remote_system

Once established the RDP connection will span two HD monitor side by side.
Using /w width and /h height you have to define the span based on your monitor arrangement (physical to the system from which you initiate a remote cnnection without regard what is physically connected to the remote system)

Okay, I see a large blue screen.  I guest it's acting as 1 screen, and I just have to move the various open apps (like Outlook, MS Word, etc.) according ly.

Yes, iwhen you define a span larger than your available monitors, you will get scroll bars horizontal/verticle..

If you only have one monitor, I'd suggest to use a single span that fits your monitor.

The positioning of multiple windows across a large span will require you to search the span for the window. It could become regions as often the window you are looking for could be minimized.

Single monitor, is fairly straightforward, taskbar activate the spp you want,

The issue with laptops is the size of the display.
If you can, connect it to another monitor. Many smart tvs that are wirelessly connected could be projected to
Windows key+p if not mistaken.
