Answer:
If the roots are not real,such as 1+Ian's 1+I,whose product is 2,one could determine an equation,like x²-2x+2,but 2 and 1 could be roots as well,and that equation is x²-3x+2
No;u can't tell what the equation is?
suppose the roots are p and take the equation
(x-p)=(x-q=0
x²-px-qx+pa=0
x²-(p+q)=x+pq=0
