Spidey dear,

                   haven't you read what I have written?????????

Who the hell told you that 1+b+c will be equal to 0 when b= -2 and c= 1.?????

Of course that is a case, but this is not valid here.

But there are other possible values of b and c such that b<-2 and c>1, yet 1+b+c=0.

I even gave an example, and I am giving it here again:-

Consider the expression x²-3x+2;

where b= -3 which is obviously less than -2, and c=2, which is also obviously greater than 1, yet 1+b+c=1-3+2=0.

GOT IT????????

[correct me if I am wrong]

 

If I am correct please rate me {I am currently in need of some good rates, pal. Please help}
