I've an exercise where I've to design an unbalanced differential amplifier, and I'm given the circuit below and told that it's the basic one. I'm then asked to have the appropriate bias resistors. enter image description here

Are these resistors that I should add or do they correspond to Rc and Re? And how can I choose the appropriates values? (I'm free to choose all the characteristics of the circuit so I'm a bit lost)

Edit: I added voltage divider resistors R1 and R2 for biasing, and a capacitor to isolate the DC value of Vin from its AC value. Is this new circuit correct? enter image description here

Biasing resistors for differential amplifier
