Example-1- Write the solution set of the equation x2+x-2=0. Solution- x2-x+2x-2=0 x(x-1)+ 2(x-1)=0 (x-1)(x+2)=0 x=1 , x= – 2 S={1, -2} Example-2- Write the set {x: x is a positive integer and x2<40} Solution- S={1, 2, 3, 4, 5, 6} 7, 8, 9, 10, ………… can not be included because their squares are greater than […]
