MATHEMATICS NCERT EX-1.1 EXAMPLE 

1: Write the solution set of the equation x2 + x – 2 = 0 in roster form.

Sol: The given equation can be written as (x–1) (x+2)=0,i.e., x=1,–2

Therefore, the solution set of the given equation can be written in roster form as {1, – 2}.

Explanation: 

The equation x^2 + x - 2 = 0 can be factored by finding two numbers that multiply to -2 (the constant term) and add to 1 (the coefficient of x).

• The two numbers that satisfy this are 2 and -1, so

(x + 2)(x - 1) = 0

Set each factor equal to zero and solve for x:

1. x + 2 = 0 so x = -2

2. x - 1 = 0  so x = 1

The solutions to the equation are x = -2 and x = 1.

Therefore, the solution set in roster form is:

{-2, 1}
