1.	C) Write given set in roster form A={x:x2-4x-5=0}Question 2
Answer» SET will have the elements as the SOLUTIONS of x 2 −4x−5=0 =>x 2 −5x+x−5=0 =>x(x−5)+1(x−5)=0 =>(x=5,−1) So, the set is { 5,−1 }

Answer» SET will have the elements as the SOLUTIONS of x

2 −4x−5=0

=>x

2 −5x+x−5=0

=>x(x−5)+1(x−5)=0

=>(x=5,−1)

So, the set is { 5,−1 }
