In this lesson you learned to check the sign of a polynomial’s leading coefficient. 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, not from the textbook, that has at least one undefined value and show it in factored form.

    What is your question and why are you asking it? (I'm playing just tell me what you're asking). |dw:1441705022287:dw|

    Oh I don't think I can actually do this answer. Sorry! :-) Well actually let me think about it first and I will answer the question for you in a PM ok?

    This will take some time for me to figure out....

    Hmm I think a polynomial is always well defined, it's exponents can take any value of whole number {0,1,2,3,....} \[p(x)=-\frac{5}{29}x^4+77x^3+\sqrt{34}x^2-\frac{1}{2^{\frac{1}{3}}}x-\sqrt{163}\] Like this you can think many other polynomials of x, no real value of x for these can make them undefined (I'm not exactly sure but that should be the case)

    I'm not 100% sure @160UTurn
