all right. We need to make an equation, knowing that Route one and route to work with a negative to negative one. So it's used this fact that if I add them negative two plus a negative one or negative two minus one, I get negative. Be over a. And if we just make a one, our lives are gonna be so much more simple because negative two minus one is negative. Three. And if it is one, that means it's negative. Be over. One negative three is equal to negative. Be over one, which is the same is negative. B. So if negative three is equal to negative, B B is equal to three. Now let's use this fact here that if I multiply these two things negative two times negative one I get see over a. But remember is one. So I basically get C negative. Two times I give one is a positive two, which is equal to see over one, which I said before is C. So there's our see value A and B value. Let's write this X squared plus B value of three x and see value of two and set it equal to zero
