Answer:
The set is {1, -3}.
Step-by-step explanation:
1. Definition of a set. A set is any collection of objects which are called its elements. If x is an element
of the set S, we say that x belongs to S and write
x ∈ S.
If y does not belong to S, we write
y 6∈ S.
The simplest way to represent a set is by listing its members. We use the notation
A = {1, 2, 4}
to denote the set whose elements are the numbers 1, 2 and 4. We can also describe a set by describing
its elements instead of listing them. For example we use the notation
C = {x : x
2 + 2x − 3 = 0}
to denote the set of all solutions to the equation x
2 + 2x − 3 = 0 .

Answer:
x³ - 5x² + 6x = 0
x (x-2) (x-3) = 0
∴ x = 0,-2,3
x ∈ [ 0 , 3 ] - {1}
x ∈ {0 , 2 , 3}
