Well I am not sure if this is the easiest way but you could try to do this.
 
Say your solutions are x=1 and x=2.
 
If you put them in an equation like this:
 
(x-1)(x-2)=0
 
You can then foil out the two quantities to get:
 
x2-3x+2=0
 
Hope this helps and if you have follow up questions post them and ill help more.
