I'm in calculus, but we're having this test on some curve sketing soon and I'm doing some practice problems that the teacher gave us. We're not allowed to use a calculator in this calculus class (except for very rare instances) so we have to know how to sketch graphs with no problem!
I'm wondering I have factored this correctly. If not, I'm wondering if someone can point me in the right direction.
Orginal Equation:
[tex]
x^3 - 3x^2-6x+8
[/tex]
My Factors
[tex]
(x+2)(x^2-2x+4) - 3x(x+2)
[/tex]
Turns into ...
[tex]
(1-3x)(x+2)(x^2 -2x + 4)
[/tex]
If anyone could help me out I would appreciate it.
Thanks!
