I want to get something like this:
Is it really easy or is there a special method to follow ?

First use 'Symetrical Difference' instead of 'Intersection' in the Geoprocessing toolbox and then in a second step do 'Union'.
The yellow triangle in 2. is spatially in the same location as in 1. yet I didn't knew how to illustrate it in a better way. I hope you get what I mean.
That should do the same thing and didn't raised any errors for me (QGIS 2.18.0 on MacOS 10.11.6)
