CONCEPT TO BE IMPLEMENTED

SET :

A set is a well defined collection of distinct objects of our perception or of our thought to be conceived as a whole

Representation of Set :

A set can be represented in following ways

(i) Statement form method

(ii) Roster or tabular form method

(iii) Rule or set builder form method

EVALUATION

Here the given set is Q = { 13 , - 13 }

Now 13 and - 13 are the roots of the quadratic equation

( x - 13 ) ( x + 13 ) = 0

⇒ x² - 13² = 0

⇒ x² - 169 = 0

So the set in Rule Method is

Q = { x : x is real number and x² - 169 = 0 }
