it would be better to study only NCERT no other book is required as told by cbse. The important point is "old is gold", so after completing NCERT go through previous year Que paper. It is recommended by me to do must to score more then 95 in maths. For getting 100 you can also refer to NCERT exampler which is also available in cbse sites

Let x1 and. x2 belong to domain. Of fx., hence, x1^2+x1 = x2^2+x2 x1^2-x2^2+x1-x2 = 0 (x1-x2) (x1+x2+1) = 0 Since, x1+x2+1 can never be equal to 0. Hence,x1-x2 = 0 x1 = x2. Therefore, f(x) is a one one Function
