How would I find p and q? It seems impossible to form any equation without p and q

I presume p,q are real.

It's just a case of following your nose.

One root's given.

Sum of roots gives you the second root in terms of p.

Sub into the product of roots and equate real/imaginary part.

Edit: Or as BabyMaths suggested below; probably easier.

Sub in 1+2i. Consider real and imaginary parts.
