So I just finished factoring a polynomial and I got:
p(x)=(x-2)(x^6-2x^5+3x^4-6x^3)
But now I have to solve the inequalities for this polynomial for p(x)>0 and p(x)<0.
I understand I have to factor it, and I got x^3(x^2+3)(x-2)^2
And then I would take the (x^2+3) and throw in some square roots and i's.
[FONT=arial, helvetica, clean, sans-serif]and I'll probably use a number line or something, I just don't know if I include the complex result of (x^2+3)?
I have to show my work so no calculator....
I'd appreciate any help. Thanks.
