Which of the following sets are equal ? (i) A = {1, 2, 3} (ii) B = {x ϵ R:x2−2x+1=0} (iii) C = {1, 2, 2, 3} (iv) D = {x ϵ R:x3−6x2+11x−6=0}.

Answer»

Which of the following sets are equal ?

(i) A = {1, 2, 3}

(ii) B = { $x ϵ R : x^{2} - 2 x + 1 = 0$ }

(iii) C = {1, 2, 2, 3}

(iv) D = { $x ϵ R : x^{3} - 6 x^{2} + 11 x - 6 = 0$ }.
