I can see of your work and everything.
00:03
It looks like you were on the right track.
00:05
But remember that this number, whatever is the highest one, that's how many roots you need.
00:12
So when we get done, we should have five roots.
00:17
Okay, so we got to factor it down first.
00:19
So i'm going to take out an x cubed, and we get x to the fifth, or not x to the fifth, x squared, minus nine.
00:30
And then x squared minus nine is the difference of two squares so i have x minus three times x plus three all right and then when you set each of those equal to zero you get x cubed equal zero x minus three equal zero and x plus three equal zero and then when you solve each of those sorry about that...
