If A={1,2} and B= {x ∈ R: x^2-3x+2=0} then?(a) “A” and “B” are only equivalent sets and not equal(b) “A” and “B” are equal(c) “A” and “B” are not Equivalent(d) “A” and “B” are infinite setsThe question was posed to me in an online interview.My question is from Equal Sets in chapter Sets of Mathematics – Class 11

Answer»

Right choice is (B) “A” and “B” are equal

To elaborate: The ROOTS of the equation x^2-3x+2=0 are 1 and 2 also A has the same elements, therefore, A and B are equal and equivalent as well as they have the same NUMBER of elements.
