xx^(2)+2x+1=0

Given A={x:x is a root of x^(2) -1=0} B={x:x is a root of x^(2) -2x+1=0} then

(i) If A={x:x^(2)-2x+1=0}and B={x:x^(3)-x^(2)-2x=0} , then find A cupB and A cap B (ii) If A={1,2,3,4},B={2,4,6,8} and U={1,2,3,....,9} , then verify that : (A cupB)'=A'capB' (iii) If A ={1,2,3},B={2,3,4}and U={1,2,3,4,5} , then find A' cap B' .
