Write solution set of equation x^2-3x+2=0 in roster form.(a) {1,3}(b)

1.	Write solution set of equation x^2-3x+2=0 in roster form.(a) {1,3}(b) {2,4}(c) {1,4}(d) {1,2}This question was addressed to me in a national level competition.My query is from Sets and their Representations topic in division Sets of Mathematics – Class 11
Answer» The correct choice is (d) {1,2} Easy explanation: X^2-3x+2=0 =>x^2-x-2x-2=0=>x(x-1)-2(x-1)=0 =>(x-1)(x-2)=0=>x=1,2 so, the SOLUTION set of equation x^2-3x+2=0 in roster form is {1,2}.
