Let A={x:x `in` R, `x^(2)`-5x+6=0} and B={x:x `in` R,`x^(2)=9`}
i. Write A and B in roster form.
ii. Find A`cup`B and A`cap`B.
Find A-B, B-A and verify that (A-B)`cup`(B-A)=(A`cup`B)-(A`cap`B).

Text Solution

Verified by Experts

The correct Answer is:
Thus (A-B) `cup`(B-A)=A`cup`B-A`cap`B is verified.
