If the coefficient is negative, you can factor out -1 (negative one) first. Then you can factor the rest of the expression more easily. After factoring the polynomial, how do you determine which values of the variable make the original expression undefined? Give an example of a polynomial expression, that has at least one undefined value and show it in factored form.

Question

ganpat · Answer

yes, u can do that.. and do not forget to multiply by - sign at end..

anonymous · Answer

Do you have an example of a polynomial expression?

ganpat · Answer

well, i dont have any text book with me.. so let me think.. 

In between, lets c, if some one else comes up with answer.. @waterineyes , @ParthKohli

I am not getting the question @Ganpat ??

anonymous · Answer

All I need is a polynomial expression that is in factored form. And that has an undefined value....

ganpat · Answer

say for example.. -2x2 - 2x = 0

so solving it.. - (2x2 + 2) = 0

2x2 + 2 = 0
2x (x +1) = 0
2x=0   or   x+ 1 = 0

x = 0   or x = -1

is this what u r looking for ??????
