For this question, it wants us to write the polynomial that has the following zeros and is a degree of 3.
00:08
So i am given 0, so i'm going to write them as factors.
00:12
So the way i would write them as factors is i would do the opposite.
00:19
So x plus 4, x minus 6, and x.
00:26
Okay, so how did i do that? so i know how do that? i set the factors equal to zero.
00:31
So i'm basically saying how would i get x to equal negative 4? well, i would move it back over, add 4, and that's how i got x plus 4.
00:45
Same thing with 6.
00:46
Now, zero, right? we would just set it equal to 0 and it's just 0.
00:50
So that's why that one is just x by itself.
00:53
So now what i have to do, i'm going to simplify this.
00:56
I'm going to write it.
00:57
If you wanted to do in factored form, you would just have this.
01:01
Okay, this is what would be in factored form.
01:03
If they want you to simplify it more, then you would have to foil this out...
