Okay, So for this problem, we were asked to find the sum and the product of the roots without solving the equation where the equation is X squared plus two X equals zero. Just recall before we get started at the some formula is going to be ratio minus B array and the product ratio, uh, would be CEO Rafer that formula. Oh, just taking our equation and blowing in the coefficients that are needed. We have that b is going to be to here. So we have a minus two and X where Flacco fishing. Ray is a one. And from and then for see, we don't have a sea. Here s oh, that's just going to correspond to a zero and then is your over one. If we're being technical, we can plug that in, and then that's just going to be zero
