Okay, we're going to factor out.
00:02
We have 3x squared plus 11x minus 4 equals to 0.
00:12
Now we're going to find the zeros.
00:13
We're going to change this to 2x or 3x squared plus 12x minus 1x minus 4 equals to 0.
00:25
That way we can create two groupings.
00:30
And within that two groupings, we're going to have it this way.
00:34
And we'll have a plus.
00:42
So we will be able to factor out 3x, leaving us with x plus 4.
00:50
And then we'll factor out a negative 1, leaving us with x plus 4.
00:58
It's going to give us two factors.
01:00
We're going to have 3x minus 1 times x plus 4 equals our 0.
01:09
Now 0 product property rule means either one of these factors can be 0.
01:14
So we're going to take and set them both equal to zero.
01:21
And that way we can find our zeros of this.
01:25
So here, this one's going to be x equals 1 over 3.
01:29
This will be x equals a negative 4...
