So for this question, we need to find the zeros of the function, algebraicly.
00:05
And so we're going to go ahead and use the quadratic formula to find these zeros.
00:09
So we have variables of negative b, or sorry, b, a and c, based on this formula i have written in red.
00:16
This is a quadratic formula.
00:18
And this represents a, the coefficient of x squared.
00:22
The coefficient of x represents b, so that's negative 3.
00:26
And then the constant or the end is just c.
00:29
So all we have to do is really plug in the values into this formula.
00:34
So for b, we have negative 3.
00:36
So we have negative negative 3, right? because we have negative b, plus or minus b squared, which is negative 3 squared minus 4 times a, which is 1, times c, which is negative 3...
