Question

What type is of the set A = {2, 3} and B = {x: x is solution of x2 - 5x + 6 = 0} ?

Answer 1

Answer:

disjoint set

Step-by-step explanation:

A={2,3} and B={x:x is solution ofnx2-5x+6=0}

then,

x²+5x+6=0

x(x+3)+2(x+3)=0

(x+2)(x+3)=0

x=-2 or x=-3

B={-2,-3}

then A≠B

so it is a disjoint set.
